Abstract
The photocatalytic decomposition of liquid water on Pt-loaded TiO2 (Pt/TiO2 ) catalysts was investigated. The results obtained by XPS and XRD measureme nts of the catalysts as a function of the calcination temperature as well a s the photocatalytic decomposition reactions of H2O clearly indicate that c ontrolling the oxidation state of Pt as well as the amount of loaded Pt spe cies are both important factors in the design of water-splitting photocatal ysts having high efficiency and stoichiometry.
