Ni-Zr0.92Y0.16O2.08(YSZ)-supported solid oxide cell with La0.9Sr0.1Ga0.8Mg0.2O3-δ(LSGM) thin film as the electrolyte was prepared with dip-coating and co-sintering methods. CO2/H2O co-electrolysis and CO2 electrolysis performance were studied. Initial performance measurement from 1073 to 773 K shows reasonably high open circuit voltage (OCV) with superior current densities, particularly in CO2/H2O co-electrolysis, up to −4.9 A/cm2 at 1073 K and −0.19 A/cm2 at 773 K. Product analysis suggests that H2 and CO production was attributed to both electrolysis and the reverse water-gas shift (RWGS) reaction, with almost 100 % Faraday efficiency. The H2/CO ratio in the product ranged from 1.4 to 1.5 in co-electrolysis when CO2/H2O= 1/1 gas was fed. Performance comparison at 1073 K indicated that direct CO2 electrolysis occurred, however, steam electrolysis predominately occurred under co-electrolysis conditions. The prepared cell shows good stability at −0.1 A/cm2 under CO2/H2O co-electrolysis for 200 h, with almost no change in terminal potential with minimal degradation.

Oxide perovskites, such as SrCoO3, are considered to be promising air electrode catalysts for solid oxide cells. SrCoO3 is composed of non-precious elements and possesses catalytic activity for various reactions, including an oxygen reduction and an oxygen evolution reaction. However, the catalytic activity of this material is typically limited at reduced temperatures. In this study, the catalytic activity of SrCoO3 was improved by co-doping of cerium (Ce) and samarium (Sm) at the A site (Sr site) of SrCoO3. Although Ce was considered the B-site dopant in terms of ionic size and coordination number, a small amount of Ce was successfully substituted at the Sr site, simultaneously with Sm. Oxygen reduction and evolution activity were significantly increased by substitution of a small amount of cerium (∼2.5 mol%) at the A-site. At 973 K, the maximum power density generated from the LaGaO3-supported cell with Ce-Sm co-doped SrCoO3 as an air electrode was 0.62 W cm−2 in fuel cell mode, and the current density in steam electrolysis mode at 1.5 V was 0.93 A cm−2. The increased air electrode activity could be assigned to the improvement in the surface active sites and electrical conductivity of SrCoO3 by simultaneous substitution of Ce with Sm at the A site.

Metal-supported protonic ceramic fuel cells (PCFCs) are highly attractive due to their high efficiency, reliability, and low cost. However, until now, there are limited reports on metal-supported PCFCs. In this study, a selective reduction method was used for preparing the metal-supported BaZr0.44Ce0.36Y0.2O3 (BZCY) cell. It was found that insertion of an La1−xSrxScO3 (LSSc, x = 0.1-0.25) cathode functional film (CFL) was highly effective for decreasing cathodic overvoltage and ohmic loss, leading to significant increase in power density. Among the examined compositions, La0.85Sr0.15ScO3 was identified as the optimal composition of the CFL. With this configuration, an open circuit voltage (OCV) of 1.15 V and a maximum power density (MPD) of 233 mW cm−2 were achieved at 773 K. Impedance analysis suggests that the increased power density can be attributed to the decreased overvoltage and ohmic loss in the cathode side, due to significantly increased proton conductivity in the LSSc film. This improvement is likely the result of the high concentration of H+ in the LSSc film, as indicated by thermogravimetric (TG) and Hall effect measurement. Another challenge in PCFCs is the leakage current at higher oxygen partial pressure. However, the LSSc CFL also effectively prevented H+ crossover, resulting in the OCV being almost the same as the theoretical value. Achieving near-theoretical OCV is crucial for the high energy conversion efficiency of PCFCs.

Planar type solid oxide reversible cells (SORCs) using 40 μm thick La0.9Sr0.1Ga0.8Mg0.2O3-δ (LSGM) films on porous NiO-YSZ substrates were prepared via dip-coating and co-sintering. Ce0.6Mn0.3Fe0.1O2 (CMF) and TiO2-Ce0.6La0.4O2 (Ti-LDC) served as buffer layers to prevent nickel diffusion, with Ba0.6La0.4CoO3 (BLC) as the air electrode. In SOFC mode, a typical cell exhibited maximum power densities of 0.584, 0.240, and 0.045 W/cm2 at 973, 873, and 773 K. In SOEC mode, the cell achieved the current densities of 2.21, 1.12, and 0.276 A/cm2 at 1.6 V on each temperature. Adding a porous LSGM functional layer increased performance, resulting in higher power densities of 0.873, 0.317, and 0.061 W/cm2 in SOFC mode and slightly higher current densities of 2.47, 1.30, and 0.311 A/cm2 at 1.6V in SOEC mode. This improvement is attributed to the reduced mass transport overpotential. Long-term stability tests at 973 K on cell with porous LSGM layer for 100 h showed degradation rates of 3.1 %/100 h (0.8 V, 0.75 A/cm2) and 5 %/100 h (1.2 V, 1 A/cm2), respectively. Post-characterization revealed no further Ni diffusion during operation; diffusion occurred mainly during co-sintering, which could be mitigated by shorter, higher-temperature sintering.

Solid oxide electrolysis cells (SOECs) are an important subject for storage of renewable energy such as solar or wind power. In this study, tubular type SOECs using La0.8Sr0.2Ga0.8Mg0.2O3 (LSGM) electrolyte film were prepared on NiO-Y2O3 stabilized ZrO2 (YSZ) with different porosity and it was found that the porosity of the Ni-YSZ tubular substrate is an important parameter for achieving initial high current density and also low rate of durability by preventing the pulse potential noise. The addition of cornstarch as pore-formers was effective for increasing channel size (3.9 μm of average radius) in Ni-YSZ substrate and when 15 wt% cornstarch was added for extruding NiO-YSZ substrate, the tubular cell exhibited the superior initial performance, 0.69 A cm−2 at 1.6 V in SOEC mode at 873 K. This cell also shows smaller degradation rate by suppression of the pulse potential noise and the high coulomb efficiency of H2 formation. Increase in porosity of Ni-YSZ substrate is highly important for increasing the initial performance and long-term stability of SOEC.

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.

Adsorption of methylene blue from aqueous effluents is a key technique to treat wastewater discharge from chemical industries. Toward methylene blue adsorption, porous metal-organic frameworks have been promising owing to their high surface areas and tunable porosity. The incorporation of polyoxometalates (POMs) into metal-organic frameworks has been found to facilitate methylene blue adsorption due to electrostatic interactions between the anionic polyoxometalate and the cationic methylene blue. However, it remains unclear how the customizable pore of POM@MOF hybrids affects the capture of methylene blue. In this work, we study the effect of the size and environment of metal-organic frameworks on the property of methylene blue capture for [Zr6O4(OH)4(1,4-benzenedicarboxylate)6] (UiO-66) embedding an αKeggin-type polyoxometalate [α-SiW12O40]4− (SiW12). Tuning pore size and environment based on ligand engineering of the metal-organic frameworks suggests that (i) lengthening the organic linkers and (ii) functionalization of the linker with −NO2 groups could enhance the methylene blue uptakes. Notably, an increase in the loading amounts of SiW12 on UiO-66 functionalized with −NO2 groups led to outstanding methylene blue capture, comparable to that of representative zeolites such as ZSM-5 and zeolite Y.

<p>Silica (SiO₂) porous glass materials is expected as a support in environmental fields due to transparency, high surface reactivity and so on. In this study, silica porous glass with high strength was fabricated by addition of potassium carbonate (K₂CO₃) as sintering aid and mullite as reinforcing materials. At first, a sintering condition was investigated using silica disk-type samples. A brittle amorphous silica disk with low density was obtained by firing at 1200 °C. At 1400 °C, crystallization was occurred and cristobalite formed. A small amount (∼1 wt %) of K₂CO₃ was effective to densification of amorphous silica, whereas more than 1 wt % K₂CO₃ addition accelerated the crystallization of silica. This was due to the formation of liquid phase. In addition, a highly dispersed mullite to SiO₂ matrix was effective to enhance the mechanical property. The porous structure was successfully fabricated by template method using polyurethane.</p>

<p>Cellulose nanofibrils (CNFs) exhibit excellent mechanical properties and are used to reinforce various composites. The effects of incorporating CNFs into commercial mineral trioxide aggregate (MTA) cements (NEX MTA (NEX) and ProRoot^® MTA (PR)) on the underwater setting properties, compressive strength, and flowability were estimated in this study. NEX mixed without CNFs disintegrated after water immersion. NEX mixed with CNF-suspended solutions showed good setting properties under water immersion and a similar compressive strength, which was kept in air (100% relative humidity). PR did not degrade after water immersion, regardless of the presence of CNFs, and no significant difference in the compressive strength caused by CNFs incorporation was detected. The relative flowability of the NEX mixture decreased with increasing CNFs content up to 1.0 w/v%. The application of CNF-incorporated MTA in various dental cases is promising because CNFs prevent the water-immersion-dependent collapse of some MTA cements immediately after mixing.</p>

Fine cements showed the particles about 10 μm in diameter or smaller with sharp particle size distribution curves. The setting reaction of the fine cements was rapid; therefore, a 0.1% w/v of citric acid solution was used as the retarder. The compressive strengths of the fine cements were improved compared to those of the coarse cements at both 1 and 28 days after mixing at a water/powder ratio (W/P) of 0.4. The dissolution of Sr and Al ions from fine S₃A cement was enhanced. However, the relative flowability decreases with fine grinding. Further studies on flowability, handling property are required. Additionally, the biological effects of endodontic cement should be studied both<i> in vitro</i> and <i>in vivo</i>.</p>

The synthesis of Janus-type layers, which possess front and back sides that consist of different structures, remains a major challenge in the field of two-dimensional materials. In this study, two Janus-type layered coordination polymers, namely, CuII(NEtH2)(NMe2H·H2O)CuI(CN)3 (1) and CuII(NMe2H)(NMe2H·H2O)CuI(CN)3 (2), were synthesized via a simple one-pot procedure using copper(II) nitrate and sodium cyanido in mixed solutions of dimethylamine and ethylamine. Uniquely, 1 and 2 were composed of cyanido-bridged neutral layers and exhibited a CuICuII mixed-valent state. Meanwhile, using a solution of pure dimethylamine for the synthesis yielded the monovalent three-dimensional framework (NMe2H2)[CuI2(CN)3] (3). Results indicated that the simultaneous use of two mixed amines gave rise to the controlled reduction of CuII ions during the reaction. In addition, each face of the layers was coordinated by different amines on the axial positions of the CuII sites, resulting in anisotropic Janus layers. Furthermore, the thermal expansion behavior of 2 was investigated, demonstrating that the neutral [CuICuII(CN)3] layer was relatively rigid compared with the analogous anionic [CuI2(CN)3]− layer.

The ionic conduction mechanism in M2+-doped (M: Mg, Ca, Zn, and Sr) lanthanum oxybromide (LaOBr) was investigated theoretically and experimentally. Formation energy calculations of point defects revealed that Br− ion vacancies and substitutional M2+ ions were the major point defects in M2+-doped LaOBr, while Br− ion vacancies and antisite O2− ions at Br sites were the major defect types in pure LaOBr. In the relaxed point defect models, doped Mg2+ and Zn2+ ions were displaced from the initial positions of the La3+ ions, and this was experimentally supported by crystal structural analysis. These significant atomic shifts were probably due to the strong interactions between Br− and the dopant ions. First-principles calculations and experimental analyses using X-ray photoelectron spectroscopy and X-ray absorption fine-structure spectroscopy also suggested the existence of strong interactions. The migration energy of Br− ions was calculated to be 0.53 eV, while the migration energy of O2− ions was 0.92 eV, implying that Br− ion migration via a vacancy system was more probable than O2− ion migration. The calculated association energies between MLa and VBr were 0.4-0.6 eV, suggesting that the association needed to be disrupted for Br− ion conduction. The sum of the association and migration energies was comparable to the experimental association energies of M2+-doped LaOBr.

The bonding nature of hydroxide ions in two proton-conducting oxy-hydroxides, perovskite-type Ba(Zn0.4Ta0.6)O2.9−y(OH)2y (BZT) and double perovskite-type Ba(Zn0.55W0.45)O2.9−y(OH)2y (BZW), has been studied by Fourier transform infrared spectroscopy (FT-IR) at temperatures of 40–600 ​°C. A broad absorption peak at 2500−4000 ​cm−1 attributable to O–H stretching vibration was analyzed by deconvolution into four components, assigned as two symmetric (SC) and two asymmetric (AC) proton sites in the crystal lattice. The temperature variations of peak intensities revealed a difference in proton site preference between BZT and BZW, suggesting a crucial role of B-site cationic order in the proton distribution and, thereby, the proton conductive property.

The precise control of the geometry of pottery is a challenge owing to the undesirable shrinkage and deformation observed after firing. In this study, near-zero sintering shrinkage pottery (NZS) with the sintering shrinkage (SS) of < 2.0% and pyroplastic deformation index (PI) of < 1.5 × 10−6 mm−1 was developed with varying amounts of added alumina and wollastonite. Wollastonite promotes anorthite crystallisation, thereby preventing sintering shrinkage at ∼1200 °C. The mechanism for the suppressed liquid-phase sintering of the pottery was also analysed. Moreover, NZS were obtained after firing at 1300 °C with a specific phase composition for suppressing the pyroplastic deformation. Thus, NZS was successfully prepared through liquid sintering from natural minerals. Therefore, this study provides a guide for the fabrication of earthenware, stoneware, unglazed porcelain and ceramic tiles with precise dimension and geometry. Additionally, it is also important for reducing the production loss in huge pottery and large-scale production by countering the sintering shrinkage.

Syntheses of monodisperse silica spheres (MSS) and monodisperse mesoporous silica spheres (MMSS) were studied focusing on the age of starting solutions, the solvent partitioning, and the surfactant dissolution as unconscious process factors. Aging of clear and transparent starting solutions decreased nucleation and increased the size of MSS, while the aging effect was opposite in the case of MMSS. Alcohols were used as co-solvent for alkoxides and water to dilute them. Partitioning ratio of alcohols was also a factor that changes the sphere size. Even when a surfactant is soluble in water and alcohol to readily form a transparent starting solution, the clusters consisting of solute and solvent molecules or their molecular level dissolution states may vary during aging, and thus could be a factor affecting the nucleation of nanoparticles. Aging of a methanolic solution of tetramethylorthosilicate (TMOS) containing a surfactant (C16TAC; cetyltrimethylammonium chloride) resulted in unfavorable formation of irregular (non-spherical) particles probably due to the interaction between TMOS and a moisture in the surfactant during aging.

The effect of the structural environment on the Cl⁻ ion conductivity was demonstrated in LaOCl-based solid electrolytes. By replacing the La³⁺ site with lower-valent Mg²⁺ or Ca²⁺ ions, the conductivity was enhanced owing to the formation of a Cl⁻ ion vacancy. Despite the same dopant content, the conductivity of La_0.8Ca_0.2OCl_0.8 was considerably greater than La_0.8Mg_0.2OCl_0.8. This enhancement of the conductivity was influenced by the high ionicity of the Cl⁻ ions, which facilitated the weakening of the La-Cl bond cleavage to conduct inside the lattice. The elongation of the La-La distance, associated with the Cl⁻ ion conduction, could also cause an increase of the conductivity.

A detailed investigation on the main characteristics was conducted on a novel and unique group of industrially produced mesoporous silica material. Six materials from a TMPS group were selected in the respect to their pore size ranging from 1.8 nm up to 4.2 nm. Four of the selected samples were also made with silica doping making them potentially attractive for water adsorption applications with the advantage of the pore-tuning possibilities for specific use. The surface area, pore volume and pore size distribution of these materials were established by standard nitrogen adsorption at T = 77.4 K showing typical values of mesoporous silica materials such as high surface area in the range from 600 to 750 m²g⁻¹ and pore volumes reaching 0.38 cm³g⁻¹ in the case of the smallest TMPS-1.5A and 0.98 cm³g⁻¹ in the case of the largest TMPS-4R. The wall thickness was found out regular around 1.5 ~ 2 nm with lower values attributed to bigger pore sized samples promising good structural integrity. Specific heat showed regular values through all the samples at ~ 0.85 J g⁻¹K⁻¹. Additional information on the structural characteristics and the effect on the amount of silanol group presence and the difference on regular and aluminium-doped samples were studied by means of ²⁹Si DD/MAS NMR. Additionally, elemental analysis by EDS was conducted as well. All the characteristics of the TMPS materials were compared to the standard mesoporous silica materials SBA-15 and MCM-41.

A facile solvothermal synthesis in an ethanol/acetic acid mixture for the fabrication of SnO₂ with a controllable hierarchical spherical size and micro-/mesoporosity is presented. SEM, TEM and N₂ adsorption/desorption investigation unveiled that the obtained SnO₂ spheres exhibited a particle size in the range of 0.6–1.6 μm and a pore size of about 1.4–1.9 nm depending on the volume ratio of acetic acid to ethanol in the reaction mixture, and the spheres were constructed by nanoscale particles. Due to its micro-/mesoporous structure, the SnO₂ spheres exhibited large specific surface areas over 100 m²/g. When 10 vol. % of acetic acid at 200 °C for 20 h was used for the reaction, the obtained SnO₂ possessed a higher specific surface area of 145 m²/g (SnO₂_10). The gas sensing property of SnO₂_10 without an additional noble metal co-catalyst exhibited a large toluene sensing response (R_a/R_g) of 20.2 at 400 °C, which was about 6 times higher and acceptable selectivity compared to those of other samples. The study found that the sensing performance in the SnO₂ hierarchical spheres was influenced by several factors e.g. particle morphology, pore size and specific surface area rather than only a single parameter. Therefore, a precise control of those influencing parameters may lead to the optimum sensing property. These findings are important for the further development of the micro-/mesoporous metal-based oxide as an alternative successor for toluene gas sensor material.

Ceramic sheets of Na₃V₂(PO₄)₃(NVP) with NASICON-related structure have been prepared by tape-casting method. The addition of 60Na₂O-10Nb₂O₅-30P₂O₅ glass to NVP is demonstrated to enhance markedly the density of the sintered NVP sheet and its electrical conductivity. The best densified NVP sheet with a thickness of a few tens of μm is obtained by sintering tape-casted NVP added with 5 wt% glass at 920 °C, which exhibits a total conductivity of 2.9 × 10⁻⁵ S cm⁻¹ at room temperature. A Pt | NVP sheet | Pt cell works as a tiny solid-state battery with a cell potential of 1.7 V, in which NVP acts as both cathode and anode active materials via redox reactions of V⁴⁺/V³⁺ and V³⁺/V²⁺ as well as a Na⁺ ion conducting electrolyte between the two electrode layers.

Extraction of M elements from MAX phases results in “AX” compounds in contrast to the well-defined two-dimensional (2D) materials known as MXene, which are prepared by the selective etching of A elements. Despite the extensive studies on MXene from both experimental and computational aspects, the nature of the AX compounds still remains elusive, because the electrochemical etching of M atoms from MAX significantly spoils the crystal structure, predominantly resulting in amorphous AX products. Here, we demonstrate the characterization of an S/C complex prepared by the electrochemical etching of Ti₂SC. The spark plasma sintering (SPS) technique affords a well-sintered Ti₂SC disk with high purity, which can be directly utilized as a binder-free Ti₂SC electrode. It is found that the electrochemically extracted Ti elements in NH₄F electrolyte are partially crystallized into the monoclinic titanium oxynitride, TiO_0.34N_0.74. The formed amorphous S/C compound is classified into three components: acetone-soluble volatiles including elemental sulfur, acetone-insoluble volatiles, and non-volatile species carbonizable into S-doped carbon.

A robust ceramic solid electrolyte with high ionic conductivity is a key component for all-solid-state batteries (ASSBs). In terms of the demand for high-energy-density storage, researchers have been tackling various challenges to use metal anodes, where a fundamental understanding on the metal/solid electrolyte interface is of particular importance. The Na⁺ superionic conductor, so-called NASICON, has high potential for application to ASSBs with a Na anode due to its high Na⁺ ion conductivity at room temperature, which has, however, faced a daunting issue of the significantly large interfacial resistance between Na and NASICON. In this work, we have successfully reduced the interfacial resistance as low as 14 ω cm² at room temperature by a simple mechanical compression of a Na/NASICON assembly. We also demonstrate a fundamental study of the Na/NASICON interface in comparison with the Na/β′′-alumina counterpart by means of the electrochemical impedance technique, which elucidates a stark difference between the activation energies for interfacial charge transfer: ∼0.6 eV for Na/NASICON and ∼0.3 eV for Na/β′′-alumina. This result suggests the formation of a Na⁺-conductive interphase layer in pressing Na metal on the NASICON surface at room temperature.

A mixed valence compound, sodium titanium oxide bronze (Na_xTiO₂-B), combines intriguing properties of high electric conductivity and good chemical stability together with a unique one-dimensional tunnel crystal structure available for cation storage. However, this compound has not been studied for a long period because of the strongly reductive condition at high temperature required for its preparation, which limits the morphological control such as the preparation of nanocrystals. For the first time in this paper, the topotactic synthesis of nano-sized Na_xTiO₂-B with high specific surface area (>130 m²g^-1) from TiO₂(B) nanoparticles has been demonstrated. The reaction of metastable TiO₂(B) with NaBH₄ allows carrier electrons to be doped simultaneously with incorporation of Na⁺ ions into the interstitial sites of the host Ti-O lattice at relatively low temperature. An electrochemical investigation of Li⁺- and Na⁺-ion storage behaviors suggests that the incorporated Na⁺ ions are mainly placed in the 6-fold coordination sites of bronze. In addition, optical measurements including time-resolved transient spectroscopy revealed that the doped electrons in the Na_xTiO₂-B nanoparticles are predominantly in the Ti³⁺ state and behave as a small polaron. The pelletized Na_xTiO₂-B nanoparticles shows a good electronic conductivity of 1.4 × 10^-2 S cm^-1 at 30 °C with an activation energy of 0.17 eV, which is attributable to the thermal barrier for the polaron hopping.

Rutile TiO₂ codoped with tantalum and nitrogen (TiO₂:Ta,N) was assessed as a water oxidation photocatalyst for Z-scheme water splitting driven by visible light. This material was prepared by thermal ammonolysis of TiO₂:Ta with dry NH₃ at 773 K, while samples of the oxide precursor were synthesized using a microwave-assisted solvothermal technique, applying various conditions. The photocatalytic activity of the TiO₂:Ta,N during water oxidation to O₂ from an aqueous FeCl₃ solution was found to be greatly affected by the synthesis parameters. The rate of O₂ evolution was increased upon increasing the level of Ta doping in conjunction with a highly-crystalized TiO₂:Ta precursor resulting from applying a higher temperature during synthesis of the oxide. IrO₂ loading of the TiO₂:Ta,N photocatalyst also improved the O₂ evolution activity. The optimized IrO₂/TiO₂:Ta,N photocatalyst was applied to a Z-scheme water splitting system in combination with Ru/SrTiO₃:Rh and in the presence of redox mediators (Fe^3+/2+ or [Co(bpy)₃]^3+/2+). Under AM1.5G simulated sunlight, this system exhibited a maximum solar-to-hydrogen energy conversion efficiency of 0.039%, which was nearly twice as high as the previously reported system with the use of RuO₂/TiO₂:Ta,N (0.021%).

The mesoporous C12A7 mesocrystalline microcubes were successfully prepared via the topotactic synthesis approach, which could be a versatile platform for fabricating mesoporous inorganic mesocrystals. The single-phase C3AH6 is separated into Ca(OH)₂ (to CaO afterward) and C12A7 by means of the spinodal decomposition on heating, giving rise to the cocontinuous mesoporous structure in a cubic mesocrystal after removing the byproducts. The mesopore size can be tuned simply by varying calcination temperature and/or duration time. The catalytic study reveals that the mesoporous C12A7 microcubes can work out as a good support for Ru catalyst even without reduction.
