Outline of Final Research Achievements

I synthesized and characterized Keggin- and Dawson-type di-platinum-coordinated polyoxometalates. To investigate the effects of internal elements, skeletal polyoxotungstate structures, and nitrogen-containing ligands on the photocatalytic activities of diplatinum sites, I used the platinum compounds as photocatalysts for evolution of hydrogen from aqueous triethanolamine solution under visible-light irradiation. As a result, the skeletal structure (i.e., Dawson-type structure) significantly contributed to the improvement of photocatalytic activities.
While, a new, water-soluble platinum-tungsten composite was obtained by the thermal treatment in air.
