| Outline of Final Research Achievements |
Photocatalytic and photoelectrochemical water splitting using semiconductors has received much attention recently due to the potential for the clean production of hydrogen from water utilizing solar energy. In the present research project, we have newly developed non-oxide type photocatalysts that can stably reduce and/or oxidize water under visible light irradiation. We have also developed new surface modifications that can stabilize and/or improve the activity of some existing photocatalyst material, as well as new shuttle redox of polyoxometalates.
