Title:
MOF/COF HETEROJUNCTION COMPOSITE PHOTOCATALYST, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/274268
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of the preparation of photocatalysts, and particularly relates to an MOF/COF heterojunction composite photocatalyst, a preparation method therefor and the use thereof. In the present invention, 1,3,5-triformyl phloroglucinol, 2-aminoterephthalic acid and ferrous acetate are used as reaction raw materials, and a catalyst is added thereto to prepare the MOF/COF heterojunction composite photocatalyst by means of a mechanical grinding method. The preparation method of the catalyst is simple and environmentally friendly, and the catalyst has a good degradation efficiency on pollutants in water, especially carbamazepine.
