Academic Activities
1. Seiji Ogo, Takahiro Kishima, Takeshi Yatabe, Keishi Miyazawa, Ryunosuke Yamasaki, Takahiro Matsumoto, Tatsuya Ando, Mitsuhiro Kikkawa, Miho Isegawa, Ki-Seok Yoon, Shinya Hayami, [NiFe], [FeFe], and [Fe] hydrogenase models from isomers., Science advances, 10.1126/sciadv.aaz8181, 6, 24, eaaz8181, 2020.06, The study of hydrogenase enzymes (H2ases) is necessary because of their importance to a future hydrogen energy economy. These enzymes come in three distinct classes: [NiFe] H2ases, which have a propensity toward H2 oxidation; [FeFe] H2ases, which have a propensity toward H2 evolution; and [Fe] H2ases, which catalyze H- transfer. Modeling these enzymes has so far treated them as different species, which is understandable given the different cores and ligand sets of the natural molecules. Here, we demonstrate, using x-ray analysis and nuclear magnetic resonance, infrared, Mössbauer spectroscopies, and electrochemical measurement, that the catalytic properties of all three enzymes can be mimicked with only three isomers of the same NiFe complex..

Mitsuhiro Kikkawa, Takeshi Yatabe, Takahiro Matsumoto, Ki-Seok Yoon, Kazuharu Suzuki, Takao Enomoto, Kenji Kaneko, Seiji Ogo, A Fusion of Biomimetic Fuel and Solar Cells Based on Hydrogenase, Photosystem II, and Cytochrome c Oxidase, CHEMCATCHEM, 10.1002/cctc.201700995, 9, 21, 4024-4028, 2017.11, We report an Ir complex as an anode catalyst capable of switching between a hydrogenase-type fuel-cell mode and a photosystem II-type solar-cell mode. This catalyst is connected to carbon-black-supported platinum as a cathode catalyst, which reduces dioxygen in a manner analogous to cytochrome c oxidase. Together, they make a system capable of switching between the two modes..
