TiO2 film was first prepared by Micro-Arc oxidation on TA1, and then Zn(1-x)CdxS was loaded on MAO TiO2 film by the following hydrothermal process. The structure, composition and optical property of the samples were studied by XRD, SEM and UV-vis, respectively. The photocatalytic activity of the catalysts was evaluated by splitting Na2S+Na2SO3 solution into H2. Zn(1-x)CdxS covered most part of MAO TiO2 films with the increase of the concentration of Cd2+. The sediment shape on MAO films was consequently changed from the particles to the layer structure. XRD analysis illustrated that the sulfide was well crystalized in the form of CdS when the ratio of Zn: Cd is 1:1 while the sulfide is sulfide solid solution when the ratio of Zn: Cd is 4:1. With the increase of the concentration of Cd2+, the Uv-vis absorption spectra red-shifted gradually and the best catalytic property for hydrogen production was obtained when the ratio of Zn: Cd = 1:1.
