Disclosed is a method for preparation of a photocatalyzer of high catalytic reduction activity, belonging to the art of photocatalysis. In order to decompose effectively the persistence contaminant to the environment such as the perfluorine compounds, the invention discloses a method for preparation of a photocatalyzer: firstly, pretreating the supported base material by deoiling, coating on the surface with a even Cu buffer layer of thicken of more than 5 nano, then, preparing Ni even buffer layer, and the supported substrate material being prepared. At last, preparing TiO2 precursor film on the supported substrate material, and burning by at least 20min in heat treatment device in a random temperature among 300- 600Deg. C, then the supported TiO2- CuO- NiO photocatalyzer of reducing power being prepared. The photocatalyzer prepared with said technique is characterized in that: the reducing activity is high, it is easy to separate and reclaim, the technique is simple, and it is totally suit for batch production. |
