Abstract
The application belongs to the field of material preparation and environments, and specifically, to a precious metal loaded Covalent Organic Framework (COF) composite material and a preparation method therefor. The components of the composite material include precious metal nanoparticles and TpMA. The preparation method includes first mixing the TpMA, chloroauric acid and methanol; and then adding sodium borohydride for reaction, so as to obtain the composite material. The precious metal nanoparticle loaded COF material prepared in the application may be used as a catalyst, which is a novel heterogeneous catalyst with simple, green and efficient preparation; and the material is high in catalytic activity, fast in degradation rate and short in time, and may catalyze the reduction of high concentration pollutants.
