Effect of carbonate salt addition on the photocatalytic decomposition of liquid water over Pt–TiO2 catalyst

Abstract

It has been found that an addition of carbonate salts to Pt-loaded TiO2 suspensions led to highly efficient stoichiometric photocatalytic decomposition of liquid water into H2 and O2. Neither the pH nor cation directly contributes to the water splitting, and the presence of a high concentration of carbonate ions i
