▎ 摘　　要

NOVELTY - Method for preparing silver/graphene oxide photocatalytic material, involves (a) using graphite powder for preparing graphene or graphene oxide by adopting a Hummers method, (b) grinding and uniformly mixing 1.08-4.32 g nanosheet-like structure graphene and 0.85-2.48 g silver nitrate by a mortar, and (c) placing the mixture into a tubular furnace, calcining at 500 degrees C for 6 hours under a nitrogen atmosphere, naturally cooling to obtain a sample silver/graphene oxide and putting the sample into a drying oven. USE - The method is useful for preparing silver/graphene oxide photocatalytic material as a heterogeneous catalyst in the field of waste gas and wastewater treatment and for antibacterial disinfection of composite material water environment. ADVANTAGE - The method is simple to operate. The photocatalytic material has high catalytic performance and high sterilization effect.
