NOVELTY - Preparation of graphene quantum dot-modified dysprosium-doped zinc oxide photocatalytic material, involves (S1) adding zinc acetate and dysprosium nitrate to deionized water to obtain solution (i), (S2) adding sodium hydroxide to deionized water to prepare solution (ii), (S3) adding solution (ii) to solution (i), stirring, ultrasonically treating, (S4) placing ultrasonically treated mixed solution in microwave digestion apparatus, precipitating, separating and drying to obtain dysprosium-doped zinc oxide precipitate, (S5) dispersing graphene quantum dot solution onto the surface of the precipitate by a dropping method and forming catalytic layer on the surface of the precipitate. USE - Preparation of graphene quantum dot-modified dysprosium-doped zinc oxide photocatalytic material. ADVANTAGE - The method enables preparation of graphene quantum dot-modified dysprosium-doped zinc oxide photocatalytic material with excellent catalytic performance.
