    Abstract

    Carbon dioxide (CO<sub>2</sub>) electroreduction reaction (CO<sub>2</sub>RR) offers a promising strategy for the conversion of CO<sub>2</sub> into valuable chemicals and fuels. CO<sub>2</sub>RR in acidic electrolytes would have various advantages due to the suppression of carbonate formation. However, its reaction rate is severely limited by the slow CO<sub>2</sub> diffusion due to the absence of hydroxide that facilitates the CO<sub>2</sub> diffusion in an acidic environment. Here, we design an optimal architecture of a gas diffusion electrode (GDE) employing a copper-based ultrathin superhydrophobic macroporous layer, in which the CO<sub>2</sub> diffusion is highly enhanced. This GDE retains its applicability even under mechanical deformation conditions. The CO<sub>2</sub>RR in acidic electrolytes exhibits a Faradaic efficiency of 87% with a partial current density $$( {j}_{ { { { \rm{C } } } }_{2+ } })$$ of −1.6 A cm<sup>−2</sup> for multicarbon products (C<sub>2+</sub>), and $$ {j}_{ { { { { { \rm{C } } } } } }_{2+ } }$$ of −0.34 A cm<sup>−2</sup> when applying dilute 25% CO<sub>2</sub>. In a highly acidic environment, C<sub>2+</sub> formation occurs via a second order reaction which is controlled by both the catalyst and its hydroxide.

  • Modulating Electronic States of Cu in Metal-Organic Frameworks for Emerging Controllable CH<sub>4</sub>/C<sub>2</sub>H<sub>4</sub> Selectivity in CO<sub>2</sub> Electroreduction

    The intensive study of electrochemical CO2 reduction reaction (CO2RR) has resulted in numerous highly selective catalysts, however, most of these still exhibit uncontrollable selectivity. Here, it is reported for the first time the controllable CH4/C2H4 selectivity by modulating the electronic states of Cu incorporated in metal-organic frameworks with different functional ligands, achieving a Faradaic efficiency of 58% for CH4 on Cu-incorporated UiO-66-H (Ce) composite catalysts, Cu/UiO-66-H (Ce) and that of 44% for C2H4 on Cu/UiO-66-F (Ce). In situ measurements of Raman and X-ray absorption spectra revealed that the electron-withdrawing ability of the ligand side group controls the product selectivity on MOFs through the modulation of the electronic states of Cu. This work opens new prospects for the development of MOFs as a platform for the tailored tuning of selectivity in CO2RR.

    Electrochemical reduction of CO2 (ECO2R) is gaining attention as a promising approach to store excess or intermittent electricity generated from renewable energies in the form of valuable chemicals such as CO, HCOOH, CH4, and so on. Selective ECO2R to CH4 is a challenging target because the rate-determining step of CH4 formation, namely CO* protonation, competes with hydrogen evolution reaction and the C–C coupling toward the production of longer-chain chemicals. Herein, a Cu-TiO2 composite catalyst consisting of CuOx clusters or Cu nanoparticles (CuNPs), which are isolated on the TiO2 grain surface, was synthesized using a one-pot solvothermal method and subsequent thermal treatment. The Cu-TiO2 catalyst exhibited high selectivity for CH4, and the ratio of FE for CH4 to total FE for all products in ECO2R reached 70%.

    Abstract

    The oxygen evolution reaction (OER) is a critical element for all sorts of reactions that use water as a hydrogen source, such as hydrogen evolution and electrochemical CO<sub>2</sub> reduction, and novel design principles that provide highly active sites on OER electrocatalysts push the limits of their practical applications. Herein, Au‐cluster loading on unilamellar exfoliated layered double hydroxide (ULDH) electrocatalysts for the OER is demonstrated to fabricate a heterointerface between Au clusters and ULDHs as an active site, which is accompanied by the oxidation state modulation of the active site and interfacial direct OO coupling (“interfacial DOOC”). The Au‐cluster‐loaded ULDHs exhibit excellent activities for the OER with an overpotential of 189 mV at 10 mA cm<sup>−2</sup>. X‐ray absorption fine structure measurements reveal that charge transfer from the Au clusters to ULDHs modifies the oxidation states of trivalent metal ions, which can be active sites on the ULDHs. The present study, supported by highly sensitive spectroscopy combining reflection absorption infrared spectroscopy and modulation‐excitation spectroscopy and density functional theory calculations, indicates that active sites at the interface between the Au clusters and ULDHs promote a novel OER mechanism through interfacial DOOC, thereby achieving outstanding catalytic performance.

    Although hydrogen plays a crucial role in ammonia synthesis, very little is known about its poisoning of Ru catalysts. In this study, density functional theory calculations of H2 and N2 dissociations, and H atom binding on Ru153 were performed to provide a fundamental understanding of hydrogen poisoning. Because of the kinetic dominance of the H2 dissociation over N2 (vertically or horizontally adsorbed) splitting, the dissociated H atoms block the active sites required for horizontal (less energetically demanding dissociation) N2 adsorption to occur either from the gas phase or after its geometrical transformation from being adsorbed vertically. Additionally, the dissociated H atoms withdraw electrons from the surface, which reduces the ability of the neighboring Ru atoms to donate electrons for N2 activation, hindering its dissociation and suppressing ammonia synthesis.

    An infinite number of crystal structures in a multicomponent alloy with a specific atomic ratio can be devised, although only thermodynamically-stable phases can be formed. Here, we experimentally show the first example of a layer-structured pseudo-binary alloy, theoretically called Z3-FePd₃. This Z3 structure is achieved by adding a small amount of In, which is immiscible with Fe but miscible with Pd and consists of an alternate L10 (CuAu-type)-PdFePd trilayer and Pd–In ordered alloy monolayer along the c axis. First-principles calculations strongly support that the specific inter-element miscibility of In atoms stabilizes the thermodynamically-unstable Z3-FePd₃ phase without significantly changing the original density of states of the Z3-FePd₃ phase. Our results demonstrate that the specific inter-element miscibility can switch stable structures and manipulate the material nature with a slight composition change.

    Proton exchange membrane water electrolysis (PEMWE) with high‐purity H<sub>2</sub> and O<sub>2</sub> products and swift response to electricity fluctuation is of great interest for renewable energy, chemical and pharmaceutical industries. Ruthenium oxide shows promise as an alternative to iridium oxide catalysts in PEMWE but suffers from severe anodic corrosion. Herein, a pluralistic electronic structure modulation approach is presented to address the instability issue of Ru, by in situ growing Mn<sub>x</sub>Ru<sub>1−x</sub>O<sub>2</sub> solid solution on MnO<sub>2</sub>, coated carbon fibers (Mn<sub>x</sub>Ru<sub>1−x</sub>O<sub>2</sub>/MnO<sub>2</sub>/CFs). Due to higher ion electronegativity, Mn dopants in the Mn<sub>x</sub>Ru<sub>1−x</sub>O<sub>2</sub> solid solution accept electrons, activating the Ru site. Simultaneously, the MnO<sub>2</sub> support donates electrons to prevent Ru site overoxidation and dissolution due to its lower work function than the Mn<sub>x</sub>Ru<sub>1−x</sub>O<sub>2</sub> solid solution. As a result, the Mn<sub>x</sub>Ru<sub>1−x</sub>O<sub>2</sub>/MnO<sub>2</sub>/CFs catalyst exhibits a low overpotential of 161 mV at 10 mA cm<sup>−2</sup> and a remarkable stability exceeding 600 h. Profiting by its improved oxygen evolution reaction (OER) kinetic activity, the Mn<sub>x</sub>Ru<sub>1−x</sub>O<sub>2</sub>/MnO<sub>2</sub>/CF‐based PEMWE shows a low cell voltage of 1.9 V at 2 A cm<sup>−2</sup>, and stably operate at current density of 500 mA cm<sup>−2</sup> for 24 h. This work shows the potential of the pluralistic electronic structure modulation to boost activity and stability of Ru‐based acidic OER electrocatalysts.

    Ionic liquid (IL)/solid interfaces are relevant to a broad range of physicochemical phenomena and technological processes such as catalysis, corrosion, electrochemistry, and lubrication. Hence, understanding the effect of substrate surface nature on the interfacial properties has a significant impact on improving technological processes in which interfacial properties are dominant. In this work, we investigated interfacial structures between 1-butyl-3-methylimidazolium hexafluorophosphate (BMI-PF6) IL and KBr crystal surfaces by frequency modulation atomic force microscopy utilizing a quartz tuning fork sensor. KBr(100) and (111) surfaces were used as the substrates, where the (100) surface is electrically neutral, and the (111) surface is highly charged. We investigated the influence of surface charge on their surface structures and interfacial solvation structures by atomic-scale topographic imaging and frequency shift versus distance curve measurement. The behavior of IL at these two interfaces was found to be significantly different due to these different surface properties.

    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.

    Sintering-induced aggregation of active metals is a major cause of catalyst deactivation. Catalysts that can operate above 800°C are rare. Here, we report an unusual noble metal catalyst with sintering-induced activation at temperatures up to 1,000°C. The catalyst consists of atomically dispersed palladium embedded in a reducible SnO support designated for lean methane combustion. High temperature reaction simultaneously causes favorable changes of palladium ensemble state combining synergistically with lattice oxygen activation. Such changes lead to at least one order of magnitude improvement of the intrinsic reactivity, which compensates the surface area loss. Extensive characterizations such as atom probe tomography, X-ray absorption spectroscopy, and isotope tracking together with theoretical calculations illustrate the structure and surface chemistry changes and their impacts on the reaction mechanism. The catalyst also shows notable long-term stability and facile regeneration after poisoning. Our work may provide new insights into designing active and thermally stable catalysts. 2

    Alcohol is considered as a potential CO -free energy carrier to replace hydrogen because of its high energy density, appropriate chemical stability and low-cost production. In this study, we describe the development of a simple in situ growth method to prepare a binder free IrO -Ti anode with a very low IrO loading amount (< 0.25 mg cm ), and the obtained catalyst shows a high oxygen evolution reaction (OER) activity and durability in acidic media. The performance of a polymer electrolyte alcohol electrosynthesis cell (PEAEC) using this anode catalyst shows a better performance than that of PEAEC using a typical commercial IrO -Ti paper anode with the loading of IrO = 3 mg cm . Furthermore, the key factors that affect the performance of the PEAEC are determined by comparing the performances of the PEAEC with different anode catalysts. 2 x x 2 2 −2 −2

    The accumulation of organic pollutants in surface water, groundwater, and even drinking water has raised as a serious issue in recent decades. Semiconductor-based photocatalysis has emerged as a green and sustainable approach to find remediate solutions for environmental and energy issues. However, the fast recombination rate of photogenerated charge carriers reduces the photocatalytic efficiency of photocatalysts. In this study, a hydrothermal synthesis method is proposed for preparing four types of p–n heterojunctions, BiVO /BiOX (X = F, Cl, Br, I). BiVO is an n-type semiconductor and BiOX is a p-type semiconductor. Photocatalytic activity tests showed that the BiVO /BiOF has the best photocatalytic performance under visible light, and photoluminescence spectra confirmed the lowest recombination rate of photogenerated charge carriers for BiVO /BiOF as compared with others. 4 4 4 4

    Screen printing is attracting attention as a method for manufacturing magnetic components such as on-chip transformers and inductors. Fe–Ni alloys, which have high saturation magnetizations and permeabilities, are suitable as magnetic materials for screen-printed high-frequency devices. Here, we demonstrate the fabrication of a screen-printed film comprising solid-solution Fe–Ni nanoalloys, which can achieve enhanced permeability and reduced eddy-current losses in high-frequency regions. The Fe–Ni nanoalloys were prepared by chemical reduction using sodium borohydride as a reducing reagent followed by hydrogen reduction. X-ray diffraction measurements, electron microscopy, and inductively coupled plasma spectroscopy revealed that well-mixed Fe Ni nanoalloys (x = 40, 21.5, and 10) with grain sizes of ~ 10 nm were synthesized. The obtained nanoalloys showed high saturation magnetizations comparable to bulk alloys. The screen-printed film using the Fe Ni nanoalloy exhibited the highest permeability of the nanoalloy films. The eddy-current loss was suppressed by the synthesis of nanoscale-grained nanoalloys. The permeability was sufficiently high for application in transformers and inductors. x 100−x 21.5 78.5

    To recycle ethylene glycol (HOCH CH OH) fuel in alkaline fuel cells, active and selective catalysts for partially oxidizing HOCH CH OH to glycolic acid (HOCH COOH) and oxalic acid ((COOH) ) are required at the anode; in other words, complete oxidation of HOCH CH OH to CO prevents ethylene glycol recycling. We investigate catalyst activity and selectivity for oxidizing HOCH CH OH to HOCH COOH on Fe(0 0 1), Co(0 001), and Ni(1 1 1) via first-principles calculations. We calculate the oxidation reaction path from HOCH CH OH to HOCH COOH without C–C bond dissociation to avoid CO generation. Partial oxidation of HOCH CH OH to HOCH COOH without C–C bond dissociation proceeds as follows: O–H bond dissociation of HOCH CH OH to generate HOCH CH O; C–H bond dissociation of HOCH CH O to generate HOCH CHO; C–H bond dissociation of HOCH CHO to generate HOCH CO; and OH addition to HOCH CO to generate HOCH COOH. The activation energies for O–H bond dissociation of HOCH CH OH and C–H bond dissociation of HOCH CH O and HOCH CHO on Fe(0 0 1) are 20.2, 22.8, and 35.2 kcal/mol, respectively, which are the lowest of the three surfaces. Thus, Fe(0 0 1) is most active. To determine the selectivity, we compare the bond dissociation activation energies. The activation energies for C–C bond dissociation of HOCH CH OH and HOCH CH O on Fe(0 0 1) (66.7 and 39.5 kcal/mol, respectively) are higher than those for O–H bond dissociation of HOCH CH OH (20.2 kcal/mol) and C–H bond dissociation of HOCH CH O (22.8 kcal/mol), implying that the O–H bond of HOCH CH OH and C–H bond of HOCH CH O dissociate before the C–C bond dissociation during oxidation on Fe(0 0 1). In contrast, the activation energies for C–H and C–C bond dissociation of HOCH CHO (35.2 and 32.8 kcal/mol, respectively) are similar. The C–H and C–C bonds therefore dissociate during HOCH CHO oxidation. On Co(0 0 0 1) and Ni(1 1 1), the activation energies for C–C bond dissociation of HOCH CH O and HOCH CHO are lower than those for their C–H bond dissociation. Therefore, Fe(0 0 1) is more active and selective than Co(0 0 0 1) and Ni(1 1 1) for the partial oxidation of HOCH CH OH to HOCH COOH. 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2

    本学術変革領域研究では、イオン伝導体、触媒、蓄電池材料などにおけるイオンの集団運動効果を数理科学により解き明かすことを領域目標としている。この実現に向けて、計画研究A03は高度な計測技術を複合的に活用することで、イオンの集団運動を捉えることを目的とする。A02より提供される高品質なモデル材料に対して、イオンが実際に流れる状態を創り出し、複数のプローブ・計測技術を組み合わせることでイオンダイナミクスを多角的に評価する（オペランドマルチモーダル計測）。
    以上の取り組みにより、これまで未解明であったイオン流を計測により明らかにし、さらに、理論家と材料合成研究者を巻き込んだ新たな研究の進め方を構築する。
