Bi3O4Cl/BiOBr composite heterojunction photocatalyst was prepared using in-situ generation method. A number of characterisation techniques were used to examine the prepared material's crystal structure, microstructure, elemental content, and optoelectronic characteristics. By breaking down the antibiotic ofloxacin in the presence of visible light, the produced photocatalyst's degradation activity was investigated. According to the experimental findings, a composite photocatalyst has a higher degrading activity than a photocatalyst made of a single component. The optimal composite sample BBC-2 has apparent rate constants that are 4.3 times and 3 times higher than those of pure BiOBr and Bi3O4Cl, respectively. The 4 cycles of experiments indicate that the composite sample has good stability. According to the electrochemical test results, it was found that the Bi3O4Cl/BiOBr composite photocatalyst has good photo generated carrier separation efficiency and excellent charge transfer efficiency, thus exhibiting good degradation activity towards ofloxacin. Superoxide radicals and holes are the primary active species in Bi3O4Cl/BiOBr composites in photocatalytic tests, according to the free radical capture experiment. In addition, charge transfer pathways and mechanisms for enhancing activity were proposed through free radical capture experiments and band theory.
