NOVELTY - Preparation of cadmium sulfide-graphene-zinc sulfide composite material in two phases using graphene oxide as emulsifier involves using raw material solutions which are not soluble in hydrophilic and lipophilic amphiphilic emulsification of graphene oxide through single-step solvothermal reaction, depositing cadmium sulfide and zinc sulfide on two sides of graphene oxide, and reducing the graphene oxide to graphene. USE - Preparation of cadmium sulfide-graphene-zinc sulfide composite material in two phases using graphene oxide as emulsifier for photocatalytic applications. ADVANTAGE - The method is simple to operate, and the content of compound can be controlled by adjusting the concentration of reaction solution, so that the photocatalytic performance of the material is changed. The prepared composite material has excellent performance of producing hydrogen peroxide through photocatalysis, and degrading tetracycline through photocatalysis.
