Research Abstract

Four-electron water oxidation is a necessary for realization of artificial photosynthesis. In this research, we developed mono- and binuclear complex catalysts for the purpose of four-electron water oxidation near the equilibrium potential. We have synthesized the mono-ruthenium complexes having a strong electron donor ligand, such as tetramethylethylenediamine (tmen) or dipyridylbenzene (dpb). These mono-ruthenium complexes have been oxidized at lower potential compared with that of the corresponding ruthenium complex having the electron acceptor ligand. In fact, these complexes have catalyzed water oxidation in the presence of [Ru(boy)]3+ (bpy = bipyridine) as an oxidant. Furthermore, we synthesized dinuclear ruthenium complex with a phosphate group in order to develop the hybrid catalyst of metal-oxide and metal complex. Electrochemical measurements have revealed that the dinuclear ruthenium complex modified on ITO electrode shows reversible redox reaction.
