Research Abstract

There is much attention to water-oxidation catalyst from a view point of environmental and energy problems. In this project, dinuclear ruthenium complex was prepared as a water oxidation catalyst. The mechanism of O-O bond formation from two water molecules was elucidated by a spectroscopic analysis.
