    Direct decomposition of nitric oxide (NO) on metal oxides under microwave (MW) irradiation was investigated and it was found that the most metal oxides show higher NO decomposition activity than that in the conventional electric furnace heating at low temperature. Among the examined oxides, it was found that TiO2, CeO2, ZrO2, and Y2O3 show about 95 % or higher NO conversion at 573 K, and both N2 and O2 are formed with almost equimolar amount. In particular, ZrO2 exhibited high and stable NO decomposition activity more than 25 h. In this study, the influence of coexisting gases on NO decomposition activity on ZrO2 under microwave heating was further investigated and the direct decomposition of NO can be proceeded even in the presence of 5 % O2, 5 % CO2, or humidified condition. Mechanism of high NO decomposition activity under MW irradiation was also studied and it was found that removal of oxygen from the catalyst was much increased under MW irradiation because of direct activation of oxygen and also direct activation of NO which is also suggested by pulse reaction.

    Designing a highly efficient fuel electrode for CO2/H2O co-electrolysis with controllable CO/H2 ratios is fundamentally challenging due to the significant influence of water-gas shift (WGS) reaction. Perovskite oxide La0.6Sr0.4Fe0.8Mn0.2O3 (LSFM) has been identified as a promising alternative to conventional Ni-based cermet electrodes, offering inherent redox stability. In this study, LSFM exhibits efficient electrocatalytic activity and remarkable syngas control, with ratios directly controlled by adjusting the CO2/H2O feed. In-situ/ex-situ catalytic analyses reveal LSFM's efficacy in controlling syngas, attributed to substantial CO2 adsorption on its surface. The carbonated surface interacting with H2O leads to the formation of bicarbonate species, acting potential active intermediates that facilitate CO2 electroreduction to CO while suppressing the WGS reaction. Stable syngas control is confirmed by long-term reversible operations at various applied currents with nearly 100 % Faradaic efficiency. This study highlights the great potential of LSFM perovskite for efficient and steady syngas production in co-electrolysis, providing insights into advanced fuel electrode design.

    Ultrafine-grained and heterostructured materials are currently of high interest due to their superior mechanical and functional properties. Severe plastic deformation (SPD) is one of the most effective methods to produce such materials with unique microstructure-property relationships. In this review paper, after summarizing the recent progress in developing various SPD methods for processing bulk, surface and powder of materials, the main structural and microstructural features of SPD-processed materials are explained including lattice defects, grain boundaries and phase transformations. The properties and potential applications of SPD-processed materials are then reviewed in detail including tensile properties, creep, superplasticity, hydrogen embrittlement resistance, electrical conductivity, magnetic properties, optical properties, solar energy harvesting, photocatalysis, electrocatalysis, hydrolysis, hydrogen storage, hydrogen production, CO2 conversion, corrosion resistance and biocompatibility. It is shown that achieving such properties is not limited to pure metals and conventional metallic alloys, and a wide range of materials are currently processed by SPD, including high-entropy alloys, glasses, semiconductors, ceramics and polymers. It is particularly emphasized that SPD has moved from a simple metal processing tool to a powerful means for the discovery and synthesis of new superfunctional metallic and nonmetallic materials. The article ends by declaring that the borders of SPD have been extended from materials science and it has become an interdisciplinary tool to address scientific questions such as the mechanisms of geological and astronomical phenomena and the origin of life.

  • Conversion of Cellobiose to Formic Acid as a Biomass‐Derived Renewable Hydrogen Source Using Solid Base Catalysts

    Abstract

    Formic acid is considered a promising hydrogen carrier. Biomass‐derived formic acid can be obtained by oxidative decomposition of sugars. This study explored the production of formic acid from cellobiose, a disaccharide consisting of d‐glucose linked by β‐glycosidic bonds using heterogeneous catalysts under mild reaction conditions. The use of alkaline earth metal oxide solid base catalysts like CaO and MgO in the presence of hydrogen peroxide could afford formic acid from cellobiose at 343 K. While CaO gave 14 % yield of formic acid, the oxide itself was converted to a harmful metal peroxide, CaO<sub>2</sub> after the reaction. In contrast, MgO could produce formic acid without the formation of the metal peroxide. The difficulty in selectively synthesizing formic acid from cellobiose using these solid base catalysts was due to the poor conversion of cellobiose to glucose. Using a combination of solid acid and base catalysts, a high formic acid yield of 33 % was obtained under mild reaction conditions due to the quantitative hydrolysis of cellobiose to glucose by a solid acid followed by the selective decomposition of glucose to formic acid by a solid base.

    Metal-supported protonic ceramic fuel cells were prepared, and the effects of a double columnar layer at the cathode side of BaZr0.44Ce0.36Y0.2O3 (BZCY) on power density and open-circuit voltage (OCV) were studied. The double columnar structure of Pr0.2Ce0.8O2 (PrDC) and BZCY was prepared with pulsed laser deposition. It was found that the insertion of the double columnar layer was highly effective for increasing the power density and OCV. The optimum composition of the double columnar was BZCY:PrDC = 7:3, with a thickness of 200 nm. The power density of PCFCs with the BZCY-PrDC double columnar reached 413 mW/cm2, and the OCV was approximately 1.05 V at 873 K, which is six times higher than that of a cell without a functional layer. The high power density of the cell was attributed to the decreased overpotential of the cathode. Therefore, the BZCY-PrDC double columnar layer is effective in expanding the reaction site by increasing the proton concentration at the cathodic interface.

    High-entropy oxides (HEOs), containing at least five principal cations, have recently emerged as promising photocatalysts for hydrogen production via water splitting. Despite their high potential, the impact of the cation mixtures on photocatalytic activity remains poorly understood. This study investigates the high-entropy photocatalyst TiZrHfNbTaO11 using first-principles calculations combined with experimental methods to elucidate the effects of various elements on electronic structure and water splitting performance. The results indicate that the HEO exhibits a bandgap comparable to TiO2 polymorphs rutile, brookite and anatase. Cations with lower electronegativity, such as hafnium and zirconium, provide the strongest water adsorption energy, serving as active sites for water adsorption. Additionally, the co-presence of highly electronegative cations like niobium and tantalum adjacent to hafnium and zirconium enhances charge transfer to water molecules, improving splitting efficiency. These findings suggest novel strategies for designing high-entropy photocatalysts by synergistic incorporating cations with different electronegativities.

    Improvement in durability is one of the important subjects for utilizing solid oxide electrolyzer cell (SOEC) systems widely. In SOEC stacks, separators are exposed to complexed dual atmosphere (i.e. hydrogen - steam mixed gases and oxygen rich air are on each side). In this study, the degradation phenomena of separator materials (SUS430, ZMG232G10, Crofer22APU) in SOEC dual atmosphere were investigated. The samples were exposed in SOEC dual and simple atmospheres at 700 °C for 500 h. Then, their cross sections were analyzed by X-ray diffraction and scanning electron microscopy/energy-dispersive X-ray analysis. The degradation mechanisms of the separator materials in the SOEC stack operating conditions were discussed. ZMG232G10 and Crofer22APU with high Cr content showed thin oxide layer under both the dual or single atmosphere, while SUS430 with low Cr content showed significant oxidation in the H2-steam atmosphere and on the air side under the dual atmosphere condition. The significant oxidation on the air side of the dual atmosphere of SUS430 observed in this study is a unique phenomenon under the dual atmosphere condition and not observed in a single air atmosphere.

    The generation of hydrogen as a clean energy carrier by photocatalysis, as a zero-emission technology, is of significant scientific and industrial interest. However, the main drawback of photocatalytic hydrogen generation from water splitting is its low efficiency compared to traditional chemical or electrochemical methods. Zinc oxide (ZnO) with the wurtzite phase is one of the most investigated photocatalysts for hydrogen production, but its activity still needs to be improved. In this study, an oxygen-deficient high-pressure ZnO rocksalt phase is stabilized using a high-pressure torsion (HPT) method, and the product is used for photocatalysis under ambient pressure. The simultaneous introduction of oxygen vacancies and the rocksalt phase effectively improved photocatalytic hydrogen production to levels comparable to benchmark P25 TiO2, due to improving light absorbance and providing active sites for photocatalysis without any negative effect on electron-hole recombination. These results confirm the high potential of high-pressure phases for photocatalytic hydrogen generation.

  • Nanocomposite of Nb-based binary phase for lowering the activation energy of Li<sup>+</sup> intercalation as an anode for high-performance aqueous dual-ion batteries

    Aqueous dual-ion batteries have good safety, environmental compatibility, and low cost due to the use of an aqueous electrolyte. However, water electrolysis occurs during charging at high potential, resulting in a poor cyclic stability of aqueous dual-ion batteries. Hence, novel anode materials are urgently needed to be developed for aqueous dual-ion batteries with low water electrolysis. A niobium-based binary-phase composite material is reported with a capacity of 135 mA h g−1 at a current density of 0.2 mA cm−2 and with excellent reversibility in the potential range of −1.3-0 V vs. Ag/AgCl. The activation energy of Li+ intercalation was obviously decreased because of the formation of an interface, which enhanced the Li+ intercalation reaction between FeNbO4 and MoNb12O33. In addition, the lower amount of Fe2+ in the lattice of MoNb12O33 caused localized compressive strain, which promoted fast Li+ diffusion in MoNb12O33. A full dual-ion battery of 3.0 V was constructed using the binary-phase niobium-based composite for the anode, and demonstrated a high cycle stability and an average coulombic efficiency of 91% over 300 cycles. Furthermore, considering both the electrolyte and electrode materials, the theoretical energy density of this dual-ion battery was estimated to be 250 W h kg−1, which is close to that of the current Li-ion rechargeable battery.

    High entropy oxides (HEOs) have recently emerged as potential candidates for photocatalytic CO2 conversion and H2 production driven by their high structural stability and diversified elemental compositions. However, their practical use in photocatalysis is still limited particularly due to their comparatively small light absorbance and low active surface area. In this study, CO2 conversion and H2 production of an HEO TiZrHfNbTaO11 photocatalysts, originally synthesized by high-pressure torsion (HPT), were enhanced by employing pulsed laser processing in water to effectively fragment micropowders to nanopowders. The process led to a 30 times larger active surface area and accordingly to enhanced light absorbance and higher photoelectrochemical performance for CO2 and H2O conversion. The generation of the large active surface area together with the formation of laser-induced crystal lattice defects not only enhanced the photocatalytic efficiency by at least one order of magnitude but also yielded CO, H2 and CH4 production even without requiring any additional co-catalyst. This study represents a notable step forward in developing active high-entropy photocatalysts by using new strategies such as laser fragmentation.

    [FeFe]-hydrogenase (HydA) is an active biocatalytic enzyme for solar-to-hydrogen (H2) conversion. However, stability is a main challenge that limits practical applications. This work aims to encourage the efficiency of HydA by encapsulating it in the zeolitic imidazolate framework-8 (ZIF-8) as a synthetic protective shield. The construction of HydA@ZIF-8 nanoparticles, with an average diameter of 700-1000 nm, at ambient conditions can preserve HydA activity within a spatially confined microenvironment, as characterized by scanning electron microscopy and X-ray diffraction analysis. Based on MV•+-dependent H2 production activity and kinetic analysis, both the stability and efficiency of HydA@ZIF-8 surpass those of free HydA and whole-cell biocatalysts over a wider range of pH and temperature. The achievement of robust HydA@ZIF-8 construction represents a significant step forward in the development of biocatalysts for various future applications.

    <p>A dense NiO-Fe<sub>2</sub>O<sub>3</sub> (NiFe) pellet has been developed as a potential anode-support for thin-film solid oxide fuel cells (SOFCs). However, preparation of dense NiFe is very challenging. Hole-formed NiFe pellets or porous NiFe pellets are frequently formed, which cannot be used as a support (substrate) for thin-film SOFCs. Therefore, this hole-formed NiFe support is simply wasted. In this report, we attempt to re-qualify this NiFe support to be a valuable substrate, which can be used for fabricating thin-film SOFCs. By deposition of smaller NiFe particles to cover the hole-formed NiFe support, the surface of this NiFe pellet is modified. Large holes on the surface disappear. The newly formed NiFe support can be used for fabricating a single cell with La<sub>0.9</sub>Sr<sub>0.1</sub>Ga<sub>0.8</sub>Mg<sub>0.2</sub>O<sub>3−δ</sub> as thin-film electrolyte operated at intermediate temperature. Maximum power density generated from this cell is 0.45, 0.86 and 1.28 W cm<sup>−2</sup> at 873, 923 and 973 K, respectively.</p>

    Effects of channel size in NiO-YSZ porous substrate were studied on power density in solid oxide fuel cell mode and electrolysis current in steam electrolysis mode. It was found that the cell deposited on anode substrate with larger pore diameter shows a superior performance. The LSGM cell prepared on Ni-YSZ tube with average channel diameter of ca. 2.5 μm shows the maximum power density of 0.36 W cm<sup>−2</sup> in SOFC mode and 0.42 A cm<sup>−2</sup> at 1.6 V in SOEC mode at 873 K. Spike potential noise which may be caused by insufficient gas diffusion in NiO-YSZ porous substrate was observed under constant current electrolysis condition in case of NiO-YSZ tube with narrow channel and the spike noise is suppressed by increasing channel size. NiO-YSZ tube with large channel size is also effective for increasing long term stability in electrolysis mode.

  • Photocatalytic Hydrogen Evolution of TiZrNbHfTaO<sub>x</sub> High-Entropy Oxide Synthesized by Mechano-Thermal Method

    One of the most promising solutions to slow down CO2 emissions is the use of photocatalysis to produce hydrogen as a clean fuel. However, the efficiency of the photocatalysts is not at the desired level, and they usually need precious metal co-catalysts for reactions. In this study, to achieve efficient photocatalytic hydrogen production, a high-entropy oxide was synthesized by a mechano-thermal method. The synthesized high-entropy oxide had a bandgap of 2.45 eV, which coincided with both UV and visible light regions. The material could successfully produce hydrogen from water under light, but the main difference to conventional photocatalysts was that the photocatalysis proceeded without a co-catalyst addition. Hydrogen production increased with increasing time, and at the end of the 3 h period, 134.76 µmol/m2 h of hydrogen was produced. These findings not only introduce a new method for producing high-entropy photocatalysts but also confirm the high potential of high-entropy photocatalysts for hydrogen production without the need for precious metal co-catalysts.

  • Crucial Role of Self‐Exsolved Heterostructured Cermet Nanoparticles in Highly Active Spinel Electrodes for CO<sub>2</sub>/H<sub>2</sub>O Co‐Electrolysis

    Abstract

    The versatility of the spinel (AB<sub>2</sub>O<sub>4</sub>) oxides means they are of great interest for a variety of catalysis and energy conversion applications, involving gas reactions and reforming. CuFe<sub>2</sub>O<sub>4</sub> spinel is identified as a highly efficient fuel electrode for CO<sub>2</sub>/H<sub>2</sub>O co‐electrolysis due to its promising electrocatalytic activity. To identify the actual active sites, the electrochemical characteristics, composition, chemical state, and microstructure are systematically investigated while optimizing the electrolysis performance by varying the feed gas composition. Markedly enhanced electrolysis current density is achieved under a CO<sub>2</sub>‐enriched composition of 50%CO<sub>2</sub>/10%H<sub>2</sub>O‐Ar. This promising performance is attributed to the in situ exsolution of heterostructural “Cu/Fe<sub>3</sub>O<sub>4</sub>” nanoparticles on the parent CuFe<sub>2</sub>O<sub>4</sub> surface during co‐electrolysis. Interestingly, a strong correlation of the electrolysis performance with the amount of the formed heterostructural cermet is observed. The exsolved cermet heterostructure plays a crucial role in CO<sub>2</sub>/H<sub>2</sub>O electroreduction, as also confirmed by density‐functional‐theory studies. The self‐exsolved Cu/Fe<sub>3</sub>O<sub>4</sub> nanoparticles present exceptional strength due to a strong interaction between the formed metallic Cu and Fe<sub>3</sub>O<sub>4</sub>, enabling the electrode to remain active and stable under such high electrical polarization. The excellent durability and stability of the self‐exsolved heterostructural nanoparticles are clearly confirmed by long‐term operation at high‐working voltage with an outstanding Faradaic efficiency (nearly 100%).

    The correlation between lattice strain induced by metal dispersion into grain and the cathodic overpotential is studied for increasing oxygen‐dissociation activity and improving power density of solid oxide fuel cells (SOFC) at decreased temperature. Pt or Au dispersion in Pr<sub>1.90</sub>Ni<sub>0.71</sub>Cu<sub>0.21</sub>Ga<sub>0.05</sub>O<sub>4+d</sub> (PNCG) is prepared and the 3D tensile strain is successfully induced after sintering by a mismatch in thermal expansion coefficient. Due to higher hardness and melting temperature, Pt dispersion into bulk of PNCG introduces larger tensile strain than that by Au at the same amount. In particular, at 1 mol% Pt dispersion, large tensile strain of 0.67% is induced. Overpotential of 1 mol% Pt‐PNCG cathode is 8 times smaller (35 mV) than that of PNCG (270 mV) at 800 °C and 300 mA cm<sup>−2</sup>, and it is found that the cathodic overpotential of PNCG is decreased with tensile strain on both Pt and Au dispersion. This cathodic activity enhancement appears to be related with the increased diffusivity of oxide ion in PNCG. In this study, cathodic overpotential is more significantly influenced by the induced tensile strain comparing with the intrinsic catalytic activity of the dispersed metal.

  • Hybridizing Tetraglyme to Aqueous Electrolyte with Concentrated Salts Promote Intercalation of Anions on Graphite Cathode in Dual-Ion Battery

    The amount of support salt in electrolytes determines the capacity of a dual-ion battery (DIB), and highly concentrated electrolytes are required for developing the high energy density DIB. In this study, hybrid aqueous tetraglyme (G4) electrolyte is investigated to develop high energy density aqueous DIB that is composed of carbon and Mo6S8 for cathode and anode, respectively. Impedance measurement reveals that introduced G4 increases the activation energy of the anode; however, decreases the activation energy for anion intercalation into the carbon cathode. This decreases the activation energy resulted from the G4 molecule strongly solvated to Li+ resulting in weakening anion trapped in "contact ion pair" in concentrated aqueous electrolyte. So, hybrid G4-aqueous electrolyte is useful for better electrochemical intercalation of anion. In addition, this hybrid electrolyte is highly stable by formation of stable solid electrode-electrolyte interphase on Mo6S8 anode and discharge capacity of 37 mAh g(-1), and 72% retained capacity after 500 cycles with a high average coulombic efficiency of 93% is achieved.

In this study, it was found that the addition of 3,3-diaminodipropylamine was effective for preventing the formation of a Zn dendrite in the anode resulting in a long cycle life with more than 300 cycles and a discharge capacity larger than 700 mAh/g (>85% Zn used for discharge) when Ni0.8Fe0.2Co2O4 and 8 M KOH-H2O were used for the air electrode and electrolyte, respectively. The increased cycle stability could be assigned to the change in the solvated structure of Zn2+ in the electrolyte by the strong interaction between 3,3-diaminodipropylamine and solvated water, which is suggested by Raman and Fourier transform infrared spectroscopic analyses. Ab initio molecular dynamics simulations suggest that the amine is strongly interacted with OH of solvated water molecules and changes the coordination number of Zn2+, and as result, the size of the solvated Zn2+ cluster was increased, resulting in enhanced Zn2+ mobility in the electrolyte for the uniform deposition of Zn on the anode during charge by increased mobility.

    Photobiocatalytic system has been developing as a promising approach for H2 production. Herein, the rational characteristics of biocatalysts and the role of individual components affecting the efficiency of the system were investigated. Photocatalytic studies showed that tris (2-amino-2-hydroxymethyl-1,3-propanediol) was an ideal electron donor for viologen reduction by TiO2. Biocatalytic reaction revealed that cell permeability, the redox potential of electron mediators and the cell envelope were crucial to the activity of whole-cell biocatalysts. In photobiocatalytic system, recombinant Escherichia coli with a turnover frequency of 39.43 +/- 3.77 s-1 based on [FeFe]-hydrogenase activity was a more rational biocatalyst than Anabaena variabilis. A comprehensive study found that the presence of TiO2, light and biocatalysts strongly enhanced H2 production, whereas Tris and MV2+ had less influence. A maximum rate was found at 16.73 +/- 1.03 mu mol/min with a solar-to-H2 conversion of 1.58 +/- 0.10 %. Understanding the role of each component will guide the development of high-efficient photobiocatalysis.

    Abstract

    As part of the concerted effort for development of energy storage technologies, dual‐ion batteries (DIBs) or dual‐carbon batteries (DCBs) are attracting interest, owing primarily to their eco‐friendly active materials. The use of carbon as the active materials of DCBs brings about several challenges involving capacity and stability. This contribution aims to provide an in‐depth understanding of the structural and electronic properties of Ge‐doped graphene (Germagraphene) as a novel cathode material for DCBs. Density functional theory (DFT) calculations are combined with the effective screening medium (ESM) method for analyzing the electronic and band structure of PF<sub>6</sub><sup>−</sup>anion‐adsorbed Germagraphene under a potential bias. These theoretical investigations indicate that the use of Ge as a dopant for graphene has a positive impact on the adsorption of the anion on the cathode under both neutral and electrically biased conditions.

    Titanium dioxide (TiO2) is an excellent UV-photocatalytic material that is widely used in various applications, including clean energy production, environmental remediation, and chemical production. However, the use of TiO2 is limited in the field of visible light photocatalysis due to its large bandgap and fast recombination rate between electron and hole pairs, which generally results in a low photocatalytic reaction. Defect/bandgap engineering by doping and the introduction of heterojunctions has been successfully employed to improve the photocatalytic activities of TiO2 over a wide wavelength. To apply the unconventional structured TiO2 with high photocatalytic performance to industries, the development of efficient methods for large-scale production is of high importance. Flame synthesis is a very promising method for the rapid production of nanoparticles. In this article, we summarize the latest reports on the synthesis of defective and heterostructured TiO2 using the single-step method of flame synthesis. Fundamental understandings of reactor configurations, synthesis conditions, precursor preparation and their physicochemical properties are intensively discussed.

    Excessive CO2 emission from fossil fuel usage has resulted in global warming and environmental crises. To solve this problem, the photocatalytic conversion of CO2 to CO or useful components is a new strategy that has received significant attention. The main challenge in this regard is exploring photocatalysts with high efficiency for CO2 photoreduction. Severe plastic deformation (SPD) through the high-pressure torsion (HPT) process has been effectively used in recent years to develop novel active catalysts for CO2 conversion. These active photocatalysts have been designed based on four main strategies: (i) oxygen vacancy and strain engineering, (ii) stabilization of high-pressure phases, (iii) synthesis of defective high-entropy oxides, and (iv) synthesis of low-bandgap high-entropy oxynitrides. These strategies can enhance the photocatalytic efficiency compared with conventional and benchmark photocatalysts by improving CO2 adsorption, increasing light absorbance, aligning the band structure, narrowing the bandgap, accelerating the charge carrier migration, suppressing the recombination rate of electrons and holes, and providing active sites for photocatalytic reactions. This article reviews recent progress in the application of SPD to develop functional ceramics for photocatalytic CO2 conversion.

    High-entropy oxides (HEOs), as multi-component ceramics with high configurational entropy, have been of recent interest due to their attractive properties including photocatalytic activity for H2 production and CO2 conversion. However, the photocatalytic activity of HEOs is still limited to ultraviolet light. In this study, to achieve visible-light-driven photocatalysis, 10 different heterojunctions were simultaneously introduced in the Ti-Zr-Nb-Ta-W-O system. The oxide, which was synthesized by a high-pressure torsion method and oxidation, successfully produced oxygen from water under visible light without co-catalyst addition. The photocatalytic performance was attributed to high visible-light absorption, low bandgap, appropriate band structure, presence of multiple heterojunctions and accordingly easy electron-hole separation and slow recombination. These results not only show the potential of high-entropy oxides as new visible-light-active photocatalysts, but also introduce the multiple-heterojunction introduction as a strategy to achieve photocatalysis under visible light.

    Water-acetonitrile (AN) hybrid electrolyte with high concentration of bis(trifluoromethanesulfonyl) imide (LiTFSI) and Lithium bis(fluorosulfonyl) imide (LiFSI) (LiTFSI-LiFSI=3:1, molar ratio) supporting salts are studied for the high potential and large capacity rechargeable dual-ion battery. Water-acetonitrile hybrid electrolyte (WA) shows a wide electrochemical stability window of 3.1 V in 20 m aqueous electrolyte and 3.6 V in 20 m 9LiFSI-1LiTFSI in water: AN=1:3 molar ratio electrolyte. In particular, high oxidation potential, which can be assigned to the strong solvated ionic cluster formed between AN, water and LiTFSI-LiFSI supporting salts. The dual-ion battery is assembled using the graphitic carbon (KS6) and the activated carbon (AC) as cathode and anode, respectively, and 20 m LiTFSI-LiFSI in hybrid AN-water as electrolyte. It is found that the reasonably large capacity, coulombic efficiency and cycle stability were achieved. The KS6/AC cell shows 86 mAh g(-1) at the initial cycle and 50 mAh g(-1) at 100th cycle in a voltage range of 0-3.25 V, and the average coulombic efficiency of 85% is sustained over 200 cycles. The solvated structure of water to Li+ is strengthened by addition of AN from ATR-IR and NMR spectrums analysis and this change in the solvated structure is the main reason for the increased performance of the aqueous dual-ion battery.

    The solvated structure of a highly concentrated hybrid tetraglyme (G4)-water electrolyte was studied for an increasing cycle stability and performance of a KS6 used dual-ion battery. Hybrid solvent of G4 and water with a weight ratio of 2 to 8 was able to dissolve 9LiFSI-1LiTFSI supporting salts up to 37 mol kg(-1) (37 mol kg(-1) G2W8). In spite of such high concentration of supporting salts, reasonable charge and discharge performance of dual-ion battery (discharge capacity of approximate to 40 mAh g(-1) and coulombic efficiency of 90 %) were exhibited over 300 cycles. This was attributed to the decreased hydrogen evolution reaction (HER) potential to -1.05 V vs. Ag/AgCl by addition of G4. From Fourier-transform infrared, nuclear magnetic resonance, and Raman spectroscopies, G4 molecules were more strongly coordinated to Li+ to form ion pairs of [Li(G4)(x)(H2O)(y)](+) complex in hybrid G4-water electrolyte. Co-intercalation of bis(trifluoromethanesulfonyl)imide (TFSI-) and bis(fluorosulfonyl)imide (FSI-) into graphitic carbon KS6 cathode was confirmed in hybrid aqueous electrolyte.

    CO(2 )photoreduction on photocatalysts is a nature-friendly solution to decrease the CO2 amount, but the method still has low efficiency because of difficult separation and easy recombination of charge carriers in available catalysts. In this study, a high-entropy oxynitride was introduced as an active photocatalyst for photoreduction. The material had a chemical composition of TiZrNbHfTaO6N3 and was produced by a high-pressure torsion method followed by oxidation and nitriding. It showed higher photocatalytic CO2 to CO conversion compared to corresponding high-entropy oxide, benchmark photocatalyst P25 TiO2, and almost all catalysts introduced in the literature. The high activity of this oxynitride, which also showed good chemical stability, was attributed to the large absorbance of light and easy separation of electrons and holes, the low recombination of charge carriers, and the high CO(2 )adsorption on the surface. These findings introduce high-entropy oxynitrides as promising photocatalysts for CO(2 )photoreduction.

    Highly porous and uniform sphere shape Fe powder with a nano-porous structure can be prepared successfully with a spray pyrolysis method and applied for solid oxide Fe–air rechargeable battery, which is consisted of solid oxide reversible cells using an H2O/H2redox mediator. The prepared Fe powder modified with both Cr2O3and Ce0.6Mn0.3Fe0.1O2 shows a high redox reaction rate as well as cycle stability by uniform distribution. A discharge capacity of 1100 mAh·g-Fe−1 with almost 100% coulombic efficiency was achieved at initial cycles and that larger than 800 mAh·g-Fe−1 was sustained over 20 cycles at 873 K. After the reduction of Fe powder with H2 flow so-called chemical charge, a discharge capacity of 900 mAh·g-Fe−1was recovered and stably sustained for the following 20 cycles (40 total cycles), and discharge capacity may be sustained further longer cycles at 823 K. The round-trip efficiency for charge and discharge was about 90%, which can be assigned to the high reversibility of Fe redox with nano-porous structure prepared by spray pyrolysis method.

    <p>The particle size effect of platinum nanoparticles on the conversion of methane (CH<sub>4</sub>) into hydrogen cyanide (HCN) using nitric oxide (NO) as an oxidant over the Pt supported (γ + θ)-alumina was investigated. The Pt catalysts with various average particle size in the range of 1.6 to 4.1 nm were obtained by controlling the loading amount and calcination temperature. Amount of the Pt surface sites was determined by CO titration using a pulse method and the catalytic activity was evaluated under same contact time. In case of the catalysts having small particle size (1.6-3.2 nm) of Pt, NO conversion was lower than the large one. The catalysts having large particle size (4.1-4.2 nm) exhibited high selectivity of HCN reaching 53.5 % at 1.3 % C-based yield at 400 °C over 10 wt% Pt/Al<sub>2</sub>O<sub>3</sub>. One of the reasons for higher activity with the larger Pt particles is suppression of the sequential reaction of HCN to carbon dioxide and ammonia which likely proceeded at the interface between metal and support. Pt L<sub>3</sub>-edge X-ray adsorption fine structure (XAFS) spectra showed that the small particle catalysts were covered with Pt–CN species after the reaction test. In contrast, Pt–CO was observed as main adsorbed species on the large particle catalysts, suggesting that HCN desorption process was facile for the larger Pt particle case.</p>

    A tubular type solid oxide cell which consists of a NiO-Y2O3 stabilized ZrO2 (YSZ) tubular cathode substrate, a La0.9Sr0.1Ga0.8Mg0.2O3−δ (LSGM) electrolyte film and a Sm0.5Sr0.5CoO3-δ (SSC) anode was prepared by dip-coating for CO2 electrolysis at 800 °C. Since Ni in Ni-YSZ substrate is easily re-oxidized under a pure CO2 electrolysis atmosphere, co-feeding a reductive gas was essential for avoiding Ni re-oxidation and achieving a stable and large CO2 electrolysis current under high temperature operation. It was found that co-feeding H2 is more effective for preventing re-oxidation of Ni compared with CO, however, the CO formation rate was slightly lower than that estimated amount by Faraday`s law due to a water shift reaction when H2 was used as a reductive gas. Deposition of a thin Ni-Fe cathode active layer and CeO2 nano-particles obtained by infiltration were effective for increasing the CO2 electrolysis current because of the decrease in the cathodic overpotential. In spite of the low concentration of Ce was infiltrated by using a 1 M solution with a dip process, the volume change in substrate caused by the CO2 oxidant was also measured. The CO formation rate almost corresponded to the amount estimated by Faraday`s law and the coke deposition was hardly observed in Ni-YSZ substrate after CO2 electrolysis, when 10% or 5% of CO was co-fed.

    Bismuth vanadate (BiVO4) has recently received significant attention for photocatalytic CO2 conversion due to its low bandgap and high stability, but low position of the conduction band and high electron-hole recombination rate limit its photocatalytic activity. In this study, to overcome the drawbacks of BiVO4, oxygen vacancies and lattice strain are simultaneously introduced in this oxide using a high-pressure torsion process. The processed material not only shows the low recombination rate and enhanced conduction band level but also exhibits bandgap narrowing. The oxygen-deficient and highly-strained BiVO4 shows a high photocatalytic CO2 conversion rate with an activity comparable to the P25 TiO2 photocatalyst. The enhancement of photocatalytic activity is discussed based on the modification of band structure, enhanced light absorbance, the lifetime of excited electrons, and the role of oxygen vacancies as activation sites for CO2 photoreduction. This work introduces a feasible pathway to develop active photocatalysts for CO2 conversion by lattice strain and defect engineering.

    <p>Hydrogen is expecting as an energy carrier for reducing CO<sup>2</sup> emissions that cause global warming. Pipeline supply system is considered as an efficient method for supplying hydrogen. However, when H2 pipeline becomes widespread, there is a risk of accidents caused by leaked hydrogen from the buried pipeline, and identifying the point of gas leakage is important issues from safety. In the case of hydrogen leakage under the ground, it is necessary to detect the leakage point efficiently. Assuming the sensor survey used in the current city gas supply, it is highly important knowledge of the diffusion behavior of hydrogen under the ground and atmosphere for the effectiveness and detection efficiency of the survey. In addition, when considering actual operation, underground structures (protective plates, building foundations, etc.) affect the diffusion behavior of hydrogen. In this study, we organized the fundamental knowledge about the diffusion behavior of hydrogen considering the influence of underground structures through the experiment, and verified the applicability of the survey method.</p>

    NiO-Y2O3 stabilized ZrO2 (YSZ) tubular type cell using La0.9Sr0.1Ga0.8Mg0.2O3−δ electrolyte film was prepared by dip-coating method. Effects of Ce infiltration or Ce, Ni sequential-infiltration into NiO-YSZ substrate were studied and it was found that Ce infiltration after Ni is highly effective for increasing the cell performance and the stability in fuel cell and electrolysis mode at 873 K in spite of decrease in performance by simple Ni infiltration. Cyclic operation of the fuel cell and electrolysis of LSGM tubular cell using Ce or Ce[sbnd]Ni sequential-infiltrated NiO-YSZ substrate was measured at 873 K using 17% steam-25%H2 in Ar as fuel. After 100 cycles at ±0.1 A cm−2, OCV was almost the same with the initial value. The terminal potential in SOFC operation became slightly lower with increasing cycle number in case of simple Ce infiltration. The main reason for degradation during cyclic performance seems to be assigned to the increased fuel electrode overpotential. However, degradation rate is much decreased by Ce[sbnd]Ni sequential-infiltration.

  • Photocatalytic Water Splitting on KTa(Zr)O-3 Modified with Acene-Based Organic Semiconductors

    The modification effect of acene dyes such as 6,13-bis(triisopropylsilylethynyl)pentacene (TIPS-PEN) and difuranoan-thracene derivatives on the photocatalytic water splitting activity of Pt-loaded KTa(Zr)O-3 was studied. The surface modification of KTa(Zr)O-3 powder with acene dyes was conducted with an evaporation-to-dryness method using pyridine as a solvent. TIPSPEN is the most effective dye for increasing the hydrogen formation rate on the KTa(Zr)O-3 catalyst, which became larger by 14 times. The fluorescence spectrum of the TIPS-PEN-modified catalyst revealed that the excitation energy of KTa(Zr)O(3 )was transferred to the Pt cocatalyst through the TIPS-PEN moiety. The wavelength dependence of the photocatalytic activity was investigated, and the water splitting activity was improved by irradiating with both ultraviolet and visible light comparing with the case of irradiating with only ultraviolet light. Furthermore, the water splitting reaction did not occur under visible light irradiation, which suggests that a Z-scheme-type water splitting reaction, that is, a two-step photoexcitation mechanism similar to that occuring in plant photosynthesis, proceeded on PtOx/TIPS-PEN/KTa(Zr)O-3.

    Solid oxide protonic fuel cells are one of the most efficient means of directly converting stored chemical energy to usable electrical energy. Acceptor-doped Ba(Zr, Ce)O3 perovskite-type oxides are the preferred electrolyte choice as they provide higher conductivity due to lower activation energy. While substantial progress has been made on small-sized protonic laboratory-scale cells, a considerable challenge has been upscaling robust planar-type devices. This paper employs a cost-effective inverse tape casting route and screen printing to fabricate flat planar anode-supported protonic fuel cells consisting of NiO-SrZr0.5Ce0.4Y0.1O3-δ substrate, SrZr0.5Ce0.4Y0.1O3-δ electrolyte, and BaCo0.4Fe0.4Zr0.1Y 0.1O3-δ as the cathode. The processing parameters were analyzed and adjusted to obtain defect-free single cells of dimension up to 100 mm × 100 mm × 0.5 mm with diminished warping. In addition, the smooth tri-layered green tapes yielded suitably dense and gas-tight electrolyte layers after co-sintering at 1300 °C/5 h. Finally, the electrochemical performance of the 50 × 50 mm2 SrZr0.5Ce0.4Y0.1O2.95 based cells was evaluated, and their impedance spectra were deconvoluted to identify all performance-related polarization processes via the distribution of relaxation time.

    Density functional theory calculations were performed to elucidate the origin of catalytic activity of the pristine LnO-terminated surfaces of two Ruddlesden-Popper phase oxides of industrial interest. The direct comparison of molecular oxygen interaction with La2NiO4and Pr2NiO4allowed us to evaluate the electronic effect on the oxygen reduction reaction energetics. We have further addressed the surface catalytic activity as a function of interstitial oxygen occupancy in the rock salt layer and provided a possible explanation for the limits of the interstitial oxygen concentration. The oxide ion transport in the rock salt layer was compared for La2NiO4.125and Pr2NiO4.125. The diffusion difference was attributed to the electronic structure of the valence shells of Pr and La. The different polarizability of those elements would lead to the opposite effect on the transition state stability. In-depth understanding of the La2NiO4and Pr2NiO4(including La2NiO4.125and Pr2NiO4.125) electronic properties allowed us to refer electronic and hole conductivities to the computed band gaps and the electronic structure of the valence bands. Our study shows that while La2NiO4and Pr2NiO4share a similar crystallographic structure, the most important properties, such as surface catalytic activity, ionic diffusivity, and electron transport, are a direct consequence of the valence shell structure of the Ln cations: La and Pr.

    <p>Hydrogen can be considered as an energy carrier used to reduce CO2 emissions that affect greenhouse gases. As one of the efficient hydrogen supply forms, there is a supply system using pipelines. However, considering the spread of this system, there is a risk of accidents due to hydrogen leakage, and ensuring its safety is an important issue. Until now, there are few papers that consistently evaluate the diffusion in the ground and in the atmosphere of hydrogen when it leaks from buried pipes assuming actual operation. Therefore, it is strongly required to examine the safety risks under these conditions. In this paper, we organized the basic knowledge about the diffusion behavior of hydrogen when it leaked from the buried pipe by experiments, and presented the applicable analysis method. This knowledge is expected to be useful when examining the safety risks of system that supply hydrogen by pipelines in the future.</p>

    The hydrogenation of CO2 into methanol has attracted much attention and In2O3 is a promising catalyst. Introducing metal elements into In2O3 (M/In2O3) is one of the main strategies to improve its performance. However, its mechanism and active sites remain unclear and need to be further elucidated. Here, the noble-metal-free Inx-Coy oxides catalysts were prepared. Much-improved performance and obvious product selectivity shift were observed. The optimized catalyst (In1-Co4) (9.7 mmol gcat−1 h−1) showed five times methanol yields than pure In2O3 (2.2 mmol gcat−1 h−1) (P = 4.0 MPa, T = 300 °C, GHSV = 24000 cm3STP gcat−1 h−1, H2:CO2 = 3). And the cobalt-catalyzed CO2 methanation activity was suppressed, although cobalt was most of the metal element. To unravel this selectivity shift, detailed catalysts performance evaluation, together with several in-situ and ex-situ characterizations, were employed on cobalt and In-Co for comparative study. The results indicated CO2 hydrogenation on cobalt and In-Co catalyst both followed the formate pathway, and In-Co reconstructed and generated a surface In2O3-enriched core-shell-like structure under a reductive atmosphere. The enriched In2O3 at the surface significantly enhanced CO2 adsorption capacity and well stabilized the intermediates of CO2 hydrogenation. CO2 and carbon-containing intermediates adsorbed much stronger on In-Co than cobalt led to a feasible surface C/H ratio, thus allowing the *CH3O to desorb to produce CH3OH instead of being over-hydrogenated to CH4.

    Current greenhouse gas emissions suggest that keeping global temperature increase below 1.5 degrees, as espoused in the Paris Agreements will be challenging, and to do so, the achievement of carbon neutrality is of utmost importance. It is also clear that no single solution can meet the carbon neutral challenge, so it is essential for scientific research to cover a broad range of technologies and initiatives which will enable the realization of a carbon free energy system. This study details the broad, yet targeted research themes being pioneered within the International Institute for Carbon-Neutral Energy Research (I2CNER). These approaches include hydrogen materials, bio-mimetic catalysts, electrochemistry, thermal energy and absorption, carbon capture, storage and management and refrigerants. Here we outline the state of the art for this suite of technologies and detail how their deployment, alongside prudent energy policy implementation can engender a carbon neutral Japan by 2050. Recognizing that just as no single technological solution will engender carbon neutrality, no single nation can expect to achieve this goal alone. This study represents a recognition of conducive international policy agendas and is representative of interdisciplinary, international collaboration.

    The addition of 3,3,3-trifluoropropyl acetate (TFPA) to electrolyte in a Li-ion rechargeable battery (LIB) provides a means for increasing the discharge performance at low temperatures as a result of the formation of a superior solid electrolyte interphase (SEI) on the graphite anode. For instance, the addition of 2 wt% TFPA to the electrolyte significantly increased the cycle stability and the discharge capacities at low temperatures (-10°C) even at current rates of 3 C. The SEI films formed on the graphite anodes were characterized by electrochemical and spectroscopic techniques and by computational analysis. Although the formation of LiF on the anode has been recognized, present research revealed that the decomposition of TFPA on the anode surface resulted in the formation of an SEI layer consisting predominantly of organic fluorides. This layer suppressed the decomposition of the electrolyte resulting in a decreased anode impedance and an increase in cycle stability and discharge capacity at low temperatures.

    Language:English   Publishing type:Research paper (scientific journal)  

    NiO-Y2O3 stabilized ZrO2 (NiO-YSZ) supported tubular solid oxide cell, which consist of La0.9Sr0.1Ga0.8Mg0.2O3−δ (LSGM) dip-coated electrolyte film and Sm0.5Sr0.5CoO3-δ (SSC) air electrode, was prepared and power generation and electrolysis performance at intermediate temperature range were investigated. Among the rare earth oxides studied, infiltration of Ce nitrate into the substrate was the most effective for increasing cell performance in the case of 2 M infiltration. Moreover, it was found that the infiltration of higher concentration of Ce solution increased the maximum power density, because both IR loss and overpotential were significantly decreased. The maximum power density of the cell was 0.95 and 0.42 W cm-2 at 873 and 773 K, respectively at 3 M Ce nitrate infiltrated. The long-term stability of the cell was also measured by using the cell infiltrated with 1.5 M Ce, the stable power generation performance was demonstrated up to 100 h. The steam electrolysis performance of the cell using Ce infiltration was further studied and it was found that Ce also contributes to higher current density in SOEC operation and 1.07 A cm-2 at 1.6 V was achieved at 873 K using 2 M Ce infiltration.

    Language:English   Publishing type:Research paper (scientific journal)  

    Artificial photosynthesis from CO2 reduction is severely hampered by the kinetically challenging multi-electron reaction process. Oxygen vacancies (Vo) with abundant localized electrons have great potential to overcome this limitation. However, surface Vo usually have low concentrations and are easily oxidized, causing them to lose their activities. For practical application of CO2 photoreduction, fabricating and enhancing the stability of Vo on semiconductors is indispensable. Here we report the first synthesis of ultrathin WO3·0.33H2O nanotubes with a large amount of exposed surface Vo sites, which can realize excellent and stable CO2 photoreduction to CH3COOH in pure water under solar light. The selectivity for acetum generation is up to 85%, with an average productivity of about 9.4 μmol g–1 h–1. More importantly, Vo in the catalyst are sustainable, and their concentration was not decreased even after 60 h of reaction. Quantum chemical calculations and in situ DRIFT studies revealed that the main reaction pathway might be CO2 → •COOH → (COOH)2 → CH3COOH.

    The surface composition of dense La0.6Sr0.4CoO3−δ (LSC) thin film model electrodes, deposited by pulsed laser deposition at 600 °C on yttria-stabilized zirconia (100) electrolytes, was investigated by low-energy ion scattering (LEIS) and time resolved inductively coupled plasma mass spectrometry (ICP-MS). Results obtained by both methods agree qualitatively and quantitatively and provide a comprehensive picture of the surface composition and cation diffusion kinetics of LSC. The measurements revealed that freshly prepared LSC thin films already show a Sr-rich and Co-poor termination layer (80% Sr surface coverage). This Sr-rich surface layer was proven to be an equilibrium property of LSC as it forms again at elevated temperatures after removal. The kinetics of this surface reconstruction is surprisingly fast (<1 h at 550 °C) and indicates high Sr mobility in LSC. Electrochemical Impedance Spectroscopy (EIS) measurements at 400 °C revealed the detrimental effect of this surface layer on the oxygen surface exchange and suggest that higher Co concentrations in the termination layer facilitate the oxygen exchange reaction.

    Language:English   Publishing type:Research paper (scientific journal)  

    Electrical conduction properties of complex perovskite-type oxides in the (La0.5Sr0.5)(Mg0.5+yNb0.5-y)O3-δ (y = 0.02-0.06) series at intermediate-high temperatures were investigated
    introduction of protons by hydration of oxide-ion vacancies was expected by increasing the Mg/Nb ratio from unity. The conductivity depended on y and a maximum conductivity was obtained at y = 0.04: σ = 4.9 × 10-6 S cm-1 at 400 °C in wet H2 atmospheres. From electromotive force measurements of hydrogen and water vapor concentration cells, electrical conduction in wet H2 atmospheres can be attributed to ionic conduction, and proton conduction is dominant below 700 °C. Unlike other perovskite-type proton conductors, (La0.5Sr0.5)(Mg0.54Nb0.46)O3-δ was stable in CO2 atmospheres even in the low-intermediate temperature region due to dilution of reactive strontium by lanthanum. © 2008 Elsevier Ltd.

    This paper describes self-propagating high-temperature synthesis (SHS) of an electrolyte for solid oxide fuel (SOFC), in comparison to a conventional solid-state reaction method (SRM). Doped-lanthanum gallate: La0.9Sr0.1Ga0.8Mg0.2O3-δ (LSGM9182) and LSGM9173 as the SOFC electrolyte, was prepared by the SHS and sintered at different temperatures, for measuring the electrical conductivity of the sintered LSGM and the power generating performance at 1073 K, in comparison to the SRM. In the SHS, the LSGM powders with smaller size were obtained and easily sintered at the 100 K-lower temperature, 1673 K, than in the SRM. Most significantly, the electrical conductivity of the sintered LSGM9182 was as high as 0.11 S cm-1 and its maximum power density was a value of 245 mW cm-2 in the cell configuration of Ni/LSGM9182 (0.501 mm in thickness)/Sm0.5Sr0.5CoO3. The conclusion was that the proposed SHS-sintering method with many benefits of minimizing the energy requirement and the processing time in the production, easing temperature restriction for the sintering, and improving the electrolyte performance up to a conventional level is practicable for producing the LSGM-electrolyte of SOFC at an intermediate-temperature application. © 2006 Elsevier B.V.

    Oxide ion conductivity in La-deficient La2GeO5-δ was investigated with 18O tracer diffusion measurement. It was found that La1.61GeO4.415 exhibits a large diffusion coefficient, which is in good agreement with that estimated from electrical conductivity. Therefore, it was confirmed that La-deficient La2GeO5 is a pure oxide ionic conductor. The effects of doping alkaline earth cations to the La site of La1.8GeO4.7 were also investigated. Although the crystal structure was slightly changed, alkaline earth cations seem to substitute for the La site in La2GeO5. The electrical conductivity at low temperature is increased by doping alkaline earth cations, in particular, it was found that doping with Ca is the most effective for increasing the electrical conductivity. The electrical conductivity increased with increasing Ca and attained the maximum at a composition of La1.5Ca0.2GeO4.45. The transport number of the oxide ion, estimated by H2-O2 cell, was almost 1.0. Therefore, Ca-doped La2GeO5 oxide is also a pure oxide ionic conductor. Since the electrical conductivity of La1.5Ca0.2GeO4.45 was higher than that of Zr0.84Y0.15O2 at all temperature examined, Ca-doped La2GeO5 based oxide is attractive as a new fast oxide ion conductor.

     More details

    Language:English   Publishing type:Research paper (scientific journal)  

    Oxide ion conductivity in La2GeO5-based oxide was investigated and it was found that La-deficient La2GeO5 exhibits oxide ion conductivity over a wide range of oxygen partial pressure. The crystal structure of La2GeO5 was estimated to be monoclinic with P21/c space group. Conductivity increased with increasing the amount of La deficiency and the maximum value was attained at x = 0.39 in La2-xGeO5-δ. The oxide ion transport number in La2GeO5-based oxide was estimated to be unity by the electromotive force measurement in H2 - O2 and N2 - O2 gas concentration cells. At a temperature higher than 1000 K, the oxide ion conductivity of La1.61GeO5-δ was almost the same as that of La0.9Sr0.1Ga0.8Mg0.2 O3-δ or Ce0.85Gd0.15O2-δ, which are well-known fast oxide ion conductors. On the other hand, a change in the activation energy for oxide ion conductivity was observed at 973 K, and at intermediate temperature, the oxide ion conductivity of La1.61GeO5-δ became much smaller than that of these well-known fast oxide ion conductors. The change in the activation energy of the oxide ion conductivity seems to be caused by a change in the local oxygen vacancy structure. However, doping a small amount of Sr for La in La2GeO5 was effective to stabilize the high-temperature crystal structure to low temperature. Consequently, doping a small amount of Sr increases the oxide ion conductivity of La2-GeO5-based oxide at low temperature.
