▎ 摘　　要

NOVELTY - Preparing recyclable zinc oxide/graphene aerogels photocatalyst comprises preparing graphene oxide by modified Hummers' method, taking graphite powder as the raw material, and then adding prepared graphene oxide into aqueous solution of graphene oxide at a concentration of 3 mg/ml, adding 0.5-2.5 g zinc acetate, then carrying out hydrothermal reaction in the hydrothermal reactor at 160 degrees C for 10 hours to obtain hydrogel, then carrying out dialysis treatment, freezing and drying to obtain final product. USE - The method is useful for preparing recyclable zinc oxide/graphene aerogels photocatalyst (claimed). ADVANTAGE - The aerogels photocatalyst has high degradation efficiency of organic pollutants under natural sunlight; and the method has simple preparation process.
