The invention relates to a CuBi2O4/Bi2O2CO3 heterojunction type composite photocatalytic material and a preparation method thereof, and belongs to the technical field of water pollution treatment and functional materials. The CuBi2O4/Bi2O2CO3 composite material is prepared by growing Bi2O2CO3 nanosheets on CuBi2O4 microspheres in situ through a low-temperature chemical method, so that a Z-type heterojunction is constructed, and a 3D/2D hierarchical structure is formed. The composite material can adsorb organic pollutants in water and effectively degrade the organic pollutants by using visible light. After the CuBi2O4/Bi2O2CO3 is irradiated by visible light for 90 minutes, the degradation rate of the CuBi2O4/Bi2O2CO3 on a tetracycline hydrochloride solution with the concentration of 20 mg/L reaches 90%. The technology is simple and controllable, and the requirement for equipment is low. And the prepared CuBi2O4/Bi2O2CO3 adsorption-visible light catalytic material has important significance ...
