The invention discloses a Bi2O2CO3 / MIL-68-NH2
composite material as well as a preparation method and application thereof, and belongs to the technical field of photocatalytic materials and the field of
water environment treatment. According to the
composite material, Bi2O2CO3 is loaded on the surface of MIL-68-NH2, so that a
heterojunction structure is formed; the MIL-68-NH2 is a regular hexahedral rod-like
crystal with the length of 10 to 20 microns; the Bi2O2CO3 is a sphere with the
diameter of 2-3 microns, the surface of the Bi2O2CO3 is of a
carnation flower-shaped layered stacking structure, and the Bi2O2CO3 is dispersed and loaded on the surface of the MIL-68-NH2. The prepared
composite material serves as a photocatalyst to activate
persulfate under
visible light irradiation so as to degrade
antibiotics, the preparation method is simple, and the composite material has the advantages of being high in visible light
absorption capacity, stable in catalytic performance, high in degradation efficiency and the like and has potential application prospects in the field of
water treatment.
