The Cu 2+ doped porous CdIn 2 S 4 microspheres (Cu@CdIn 2 S 4 ) with better photocatalytic performance were prepared by sodium dodecyl sulphate (SDS)-assisted hydrothermal technology. The Cu@CdIn 2 S 4 were characterized by SEM, XPS, XRD and DRS. The effects of Cu 2+ doping amount on the morphology, structure and photocatalytic hydrogen production performance of CdIn 2 S 4 were studied. The porous Cu@CdIn 2 S 4 microspheres were flower shape of a average diameter of 3-5 μm and their maximum absorption edge was up to 700 nm. The Cu 2+ doping was good for the improvement of photocatalytic performance. Cu@CdIn 2 S 4 with 0.3wt% Cu 2+ doping amount possessed the highest hydrogen production rate of 1248.1 μmol/(h·g), much more than that of pure CdIn 2 S 4 .
