▎ 摘　　要

NOVELTY - Hydrothermal synthesis of tin sulfide/zinc ferrite/graphene composite photocatalyst comprises synthesizing graphene oxide using Hummers method, reducing graphene oxide using 80% hydrazine hydrate, then freeze-drying the reduced graphene oxide, adding the freeze-dried reduced graphene oxide, zinc nitrate, ferric nitrate, tin chloride and thioacetamide into deionized, stirring uniformly, regulating the pH to alkaline using an alkali, transferring the reaction mixture into a reactor, carrying out hydrothermal reaction at 160-220 degrees C for 14-24 hours, filtering, washing and drying. USE - The method is useful for hydrothermal synthesis of tin sulfide/zinc ferrite/graphene composite photocatalyst (claimed). ADVANTAGE - The method is simple and economical, produces high yield product having photocatalyzing and degrading performance.
