The invention discloses a Cu cluster loaded TiO2 water treatment catalyst as well as a preparation method and application thereof. The Cu cluster loaded TiO2 water treatment catalyst comprises 0.5-2% by mass of Cu and the balance of TiO2; the specific preparation method comprises the following steps: synthesizing ball-flower-shaped TiO2 (NFs) by using tetrabutyl titanate, N,N-dimethylformamide and isopropanol as raw materials through hydrothermal and calcination methods; then, treating TiO2(NFs), CuCl2.2H2O, KCl and LiCl as raw materials to synthesize the Cu monatomic TiO2(NFs) through a molten salt and H2 reduction method. According to the method, TiO2 with a large specific surface area is synthesized, the degradation performance is greatly improved by loading Cu clusters, meanwhile, the usage amount of metal is reduced, the efficiency of catalytic hydrogen production is high, and the application of the catalyst to green energy is promoted. 本发明公开了一种Cu团簇负载TiO2水处理催化剂及其制备方法与应用。该Cu团簇负载TiO2水处理催化剂中Cu的质量百分含量为0.5％～2
