The effect of alkali metal cation addition on the photocatalytic reaction of methanol with water over Pt-, Rh-, or Pd-loaded TiO2 catalysts

Abstract

Addition of alkali metal cations to Pt-, Rh-, or Pd-loaded TiO₂ catalysts can change the product selectivity of the photoreaction of methanol with water from hydrogen and dimethoxymethane in the case of TiO₂ catalysts free of alkali metal cations to hydrogen, methyl formate, and carbon dioxide in the case of catalysts with added alkali metal cations.
