Outline of Final Research Achievements

To establish methodology for light-driven water splitting, we have focused on the creation of highly efficient water splitting catalyst driven by light as well as the fabrication of the corresponding photoelectrochemical cell for material conversion. First, we synthesized a series of porphyrins with high oxidizing power for extracting multi-electron from the water splitting catalyst with water. Second, ruthenium complexes as the water splitting catalyst were prepared. Finally, they were assembled onto a semiconducting electrode, which was found to exhibit the capability of light-driven water splitting.
