5. Yoonyoung Kim, Motonori Watanabe, Junko Matsuda, Jun Tae Song, Atsushi Takagaki, Aleksandar Staykov, Tatsumi Ishihara, Tensile strain for band engineering of SrTiO3 for increasing photocatalytic activity to water splitting, Applied Catalysis B: Environmental, 10.1016/j.apcatb.2020.119292, 278, 2020.12, SrTiO3 is a well-known highly active photocatalyst with high energy conversion efficiency. In this study, we investigated the formation of oxygen vacancy by using the chemo-mechanical effect that was introduced by the dispersion of metal particles into grain and photocatalytic activity to water splitting. Au dispersion on SrTiO3 followed by sintering treatment was studied for introduction of chemo-mechanical strain because of a different thermal expansion coefficient; the introduced chemo-mechanical strain generated oxygen vacancy in SrTiO3. Thus, induced chemo-mechanical strain shows change in electronic band structure resulting in increasing lowest unoccupied molecular orbital (LUMO) level with increasing Au content. Since photoluminescence was significantly decreased by sintering after Au dispersion, the introduced strain effects may work for increasing a charge separation efficiency and adsorption site in water splitting. Therefore, the photocatalytic activity was much increased by sintering treatment after Au dispersion on SrTiO3..
6. Junfang Cheng, Manabu Higashi, Nobutaka Maeda, Junko Matsuda, Miho Yamauchi, Naotoshi Nakashima, CO2-free energy circulation system—Polymer electrolyte alcohol electro-synthesis cell with a low iridium content anode based on in situ growth method, Electrochimica Acta, 10.1016/j.electacta.2020.137078, 361, 2020.11, Alcohol is considered as a potential CO2-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 IrOx-Ti anode with a very low IrOx loading amount (< 0.25 mg cm−2), 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 IrO2-Ti paper anode with the loading of IrO2 = 3 mg cm−2. Furthermore, the key factors that affect the performance of the PEAEC are determined by comparing the performances of the PEAEC with different anode catalysts..

This disrupts the electron conducting network, resulting in deterioration of the electrochemical performance. It is therefore desirable to develop more robust anodes with high redox stability. Here, new cermet anodes are developed, based on nickel alloyed with Co, Fe, and/or Cr. The stable phases of these different alloys are calculated for oxidizing and reducing conditions, and their electrochemical characteristics are evaluated. Whilst alloying causes a slight decrease in power generation efficiency, the Ni-alloy based anodes have significantly improved redox cycle durability. Microstructural observation reveals that alloying results in the formation of a dense oxide film on the surface of the catalyst particle (e.g. Co-oxide or a complex Fe-Ni-Cr oxide). These oxide layers help suppress oxidation of the underlying nickel catalyst particles, preventing oxidation-induced volume changes/agglomeration, and thereby preserving the electron conducting pathways. As such, the use of these alternative Ni-alloy based cermets significantly improves the redox stability of SOFC anodes..
8. D. Kawachino, M. Yasutake, Z. Noda, Junko Matsuda, Stephen Matthew Lyth, Akari Hayashi, K. Sasaki, Surface-Modified Titanium Fibers as Durable Carbon-Free Platinum Catalyst Supports for Polymer Electrolyte Fuel Cells, Journal of the Electrochemical Society, 10.1149/1945-7111/ab9cd4, 167, 10, 2020.06, Carbon-based electrodes in polymer electrolyte fuel cells (PEFCs) are prone to corrosion. Therefore, alternative "carbon-free"materials are required. Here, the use of a catalyst-coated porous metal support is proposed as a gas diffusion electrode. As a proof-of-concept, commercially available porous titanium sheets comprising sintered titanium fibers are chemically etched with NaOH, followed by heat treatment. This results in the formation of oxidized titanium nanostructures (such as nanosheets and nanotubes) at the surface. Subsequently, platinum decoration is performed via arc plasma deposition (APD). This porous composite structure is then attached to the membrane, and used as the gas diffusion electrode for PEFC membrane electrode assemblies (MEAs). This concept integrates the catalyst, catalyst support, gas diffusion layer, and current collector in a single structure, cutting down on the number of cell components and reducing total device thickness. The carbon-free nature of this integrated gas diffusion electrode is demonstrated to successfully avoid carbon corrosion during start-stop potential cycling over 60,000 potential cycles. However, further improvements in initial electrochemical activity are still required..
