1results about How to "Improve catalysis" patented technology

The application provides a Bi2O2CO3-MIL-68(In) heterojunction composite material and a preparation method and application thereof, and belongs to the technical field of photocatalytic materials, the field of persulfate catalysis and the field of environmental governance. The composite material is obtained by loading Bi2O2CO3 on the surface of MIL-68(In) to form a Z-type heterojunction structure; the Bi2O2CO3 is a spherical body with a diameter of 200-500 nm, and the surface is a stacked granular structure; the MIL-68(In) is a regular hexahedral rhombic rod-shaped structure with a particle size of 5-10 mu m, and the Bi2O2CO3 is dispersedly loaded on the surface of the MIL-68(In). The application has the advantages of simple operation, strong visible light absorption capacity of the heterojunction material, stable photocatalytic performance, high degradation efficiency and the like, and has a potential application prospect in the field of photocatalytic persulfate.
