Hydrogen Evolution Over Heteropoly Blue-Sensitized Pt/TiO2 Under Visible Light Irradiation
We report the visible light-induced hydrogen generation over heteropoly blue (HPB) sensitized Pt/TiO2 photocatalyst. HPB was obtained via UV-induced reduction of heteropoly acid K-5(BW11O39H4) center dot A 12.8H(2)O (BW11) in glycerol aqueous solution. The photocatalytic activity for hydrogen generation was found to be dependent on the concentration of HPB in the solution.
