摘要：

(Figure Presented) Back to the elements: The activity of Pt/K 0.95Ta0.92Zr0.08O3 for the photocatalytic splitting of water into H2 and O2 is greatly improved by dye sensitization (see picture). Among the organic dyes examined, the highest photocatalytic activity is obtained with cyanocobalamin (vitamin B12) as a sensitizer. © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
