Title:
NOBLE METAL-LOADED COVALENT ORGANIC FRAMEWORK COMPOSITE MATERIAL, AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/274269
Kind Code:
A1
Abstract:
The present invention belongs to the field of material preparation and environment, and particularly relates to a noble metal-loaded covalent organic framework composite material, and a preparation method therefor. The components of the composite material include noble metal nanoparticles and TpMA. The preparation method comprises: firstly mixing TpMA, chloroauric acid and methanol; and then adding sodium borohydride to the reaction to obtain the composite material. The noble metal nanoparticle loaded covalent organic framework material prepared in the present invention can be used as a catalyst, and is a novel heterogeneous catalyst which is easy to prepare, and is environmentally friendly and efficient; same also has a high catalytic activity, a high degradation rate and a short degradation time, and can catalytically reduce high-concentration pollutants.
