Outline of Final Research Achievements

In this work, we tried to investigate the development of oxidation and reduction systems under mild conditions. As a result, we have discovered (i) new highly-active water oxidation catalysts based on the construction of the heterometallic reaction center (ii) novel oxo-bridged dinuclear ruthenium complex exhibiting alcohol oxidation activity under mild conditions (iii) photo-induced hydrogen evolution using 3d transition-metal complexes.
