Outline of Final Research Achievements

Dye-sensitized water splitting reaction allows to use a bread range of solar visible light, thus, it is suitable for complete and efficient water decomposition. On the surface of sintered electrodes of nano-titanium oxide, co-modification of various dyes and water oxidation catalysts working at low activation energy realized complete water splitting. The surface modification of the corresponding electrodes stabilizes the modified molecules on them.
Some metalloenzymes can reduce carbon dioxide at low activation energy. Dinuclear iron complex catalysts, designed by modeling of their active sites, accomplished CO2 reduction at a high energy efficiency and a large catalyst activity.
