The invention relates to the preparation of a catalyst, in particular to a preparation method and application of a TiO 2 supported copper catalyst. The preparation method of the TiO 2 supported copper catalyst includes the following steps: dissolving a titanium source and a copper salt in a solvent In the process, a precursor liquid is obtained; the precursor liquid is spray-dried and thermally polycondensed to obtain particles; the particles are calcined to obtain the TiO 2 supported copper catalyst. The present invention can simply and quickly synthesize TiO2 -supported high-dispersion low-valence copper catalyst, meanwhile, the synthesized TiO2 -supported copper catalyst exhibits a highly dispersed state, and can maintain a large amount of reduced state (Cu + /Cu) after being calcined in air 0 ), can exist stably in the air at room temperature, and can show excellent performance on photocatalytic activation of PMS to degrade pollutants in water. |
