H1-xLaNb2-xMoxO7 was prepared by solid-state reaction followed by an ion-exchange reaction. Pt was incorporated in the interlayer of H1-xLaNb2-xMoxO7 by the stepwise intercalation reaction. The H1-xLaNb2-xMoxO7 showed hydrogen production activity and the activities were greatly enhanced by Pt co-incorporating. The x value in H1-xLaNb2-xMoxO7 had an important effect on the photocatalytic activity of the catalyst. When the x=0.05, the H1-xLaNb2-xMoxO7/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 333 K.
