Abstract

Heteropoly acid such as phosphotungstic acid or silicotungstic acid was photoreduced to heteropoly blue in glycerol aqueous solution. Sensitization of Pt/TiO₂ by the heteropoly blue was found to be active for hydrogen generation under visible light irradiation. The apparent quantum yield of 3.4% for the photocatalytic hydrogen generation has been achieved with glycerol as an electron donor under 650～700 nm visible light.

Key words: heteropoly bule, visible light, photosensitization, titania
