Abstract
The present invention relates to a B-doped porous g-C3N4 catalyst, and a preparation method and application thereof, belonging to the technical field of environmental material preparation. Firstly, a catalyst precursor is prepared by simple hydrogen bond self-assembly between boric acid, melamine and cyanuric acid, and then the B-doped porous g-C3N4 is prepared by calcining in a muffle furnace, and then Fe is added to the catalyst precursor. 2+ A photocatalytic self-Fenton system was constructed, and efficient degradation and mineralization of pollutants were achieved under the synergistic effect of OH and photogenerated holes. The B-doped porous g-C3N4 prepared by the present invention simultaneously achieves B doping and morphological regulation, has enhanced charge separation and transport performance and adsorption performance for reactants, and solves the problems of low H2O2 production and insufficient enrichment of pollutants in photocatalytic self-Fenton. A 99.6% degradation rate and a 71.2% total organic carbon (TOC) removal rate of 4-chlorophenol were achieved within 50 minutes, and at the same time, it has good stability, does not produce secondary pollution, and has greatly improved safety.
