| Outline of Final Research Achievements |
Metal species that can be photodeposited with Cr on the surface of strontium titanate powder were explored. As a result, it was found that Au and Pd fit the bill, and worked as cocatalysts for hydrogen evolution in photocatalytic overall water splitting when mixed with Cr species. Detailed investigations on the Pd/Cr system indicated that the photocatalytic activity for overall water splitting depended strongly on the structure and electronic state of the Pd/Cr multicomponent cocatalyst. The mechanism by which the Pd/Cr nanoparticles were formed was also discussed on the basis of experimental results.
