| Outline of Final Research Achievements |
We studied the unique proton-coupled electron transfer (PCET) processes which are promoted at either the metal or ligand center. Specifically, we succeeded in developing the new molecular catalyst which promotes hydrogen evolution from water with the exceptionally overpotential of 173 mV by enhancing PCET at the ligand center. Furthermore, DFT calculations were performed to elucidate the factors controlling the ligand-centered PCET leading to hydrogen evolution from water. In addition, advanced electrochemical reaction analysis was performed to experimentally elucidate the reaction mechanism. On the other hand, we developed the new photochemical system which promotes hydrogen evolution from water via metal-centered PCET.
