The preparation method is simple and can be used for mass production; and the composite photocatalyst has a nuclear / shell structure, is high in adsorptive property and photocatalytic efficiency, and can be rapidly recovered through a low energy consumption method like sedimentation or atmospheric pressure filtration after the composite photocatalytic is used in a sewage medium.
