Title:
PREPARATION METHOD FOR TIO2-SUPPORTED COPPER CATALYST AND APPLICATION
Document Type and Number:
WIPO Patent Application WO/2023/272795
Kind Code:
A1
Abstract:
The present invention relates to preparation of a catalyst, and in particular to a preparation method fora TiO2-supported copper catalyst and an application. The preparation method for the TiO2-supported copper catalyst comprises the following steps: dissolving a titanium source and a copper salt in a solvent to obtain a precursor solution; performing spray drying and thermal polycondensation on the precursor solution to obtain particulate matters; and calcining the particulate matters to obtain the TiO2-supported copper catalyst. A TiO2-supported high-dispersion low-valence copper catalyst can be simply and rapidly synthesized, and meanwhile, the synthesized TiO2-supported copper catalyst exhibits a highly dispersed state, can maintain a large amount of reduction states (Cu+/Cu0) after being calcined in air, can stably exist in normal-temperature air, and can exhibit excellent performance for photocatalytic activation of PMS to degrade pollutants in water.
