Abstract

H(1-x)LaNb(2-x)Mo(x)O(7) was prepared by solid-state reaction followed by an ion-exchange reaction. Pt was incorporated in the interlayer of H(1-x)LaNb(2-x)Mo(x)O(7) by the stepwise intercalation reaction. The H(1-x)LaNb(2-x)Mo(x)O(7) showed hydrogen production activity and the activities were greatly enhanced by Pt co-incorporating. The x value in H(1-x)LaNb(2-x)Mo(x)O(7) had an important effect on the photocatalytic activity of the catalyst. When the x=0.05, the H(1-x)LaNb(2-x)Mo(x)O(7)/Pt showed a photocatalytic activity of 80 cm(3)h(-1)g(-1) hydrogen evolution rate in 10 vol.% methanol solution under irradiation from a 100 W mercury lamp at 333K.
