Abstract

The invention belongs to the field of inorganic nanometer materials and relates to a preparation method of a ZnO-loaded CdIn2S4 nano-cube composite catalyst and the application of the catalyst to the field of environmental governance. CdIn2S4 nano-cubes are synthesized by using cadmium nitrate tetrahydrate, indium nitrate monohydrate and thioacetamide as raw materials, and a ZnO-loaded CdIn2S4 nano-cube compound is synthesized through deposition and a hydrothermal method. The composite material has the advantages of large specific surface area, wide spectral response range, strong light-harvesting ability, convenience in separation of photon-generated carriers and the like and has very excellent solar photocatalytic degradation ability. A synergistic effect can be used in the ZnO-loaded CdIn2S4 nano-cube composite material, effective transfer and separation of the photon-generated carrier are realized, the light absorption range of the compound is widened, and effective degradation of tetracycline hydrochloride and ofloxacin by the compound under solar light is realized.

Description

technical field

[0001] The invention belongs to the field of inorganic nanometer materials, and relates to a ZnO loaded CdIn 2 S 4 Preparation method of nano-cube composite photocatalyst and its application in the field of environmental governance. Background technique

[0002] With the rapid development of human society, environmental pollution and energy depletion have become the primary problems that curb human progress, and photocatalytic technology based on semiconductor materials provides a new idea to solve the above problems and has received extensive attention. However, most of the current photocatalysts can only be excited by ultraviolet light (accounting for only 3-5% of sunlight) due to their wide band gap, and cannot effectively utilize visible light, which accounts for a large proportion of sunlight, resulting in very low quantum yields. low, which limits its development. Therefore, the development of semiconductor materials with high-efficiency full-band so...
