NOVELTY - Preparing gold cluster/graphene composite catalytic membrane, comprises (a) adding deionized water to the graphene oxide to be uniformly dispersed and ultrasonically dispersing to obtain a dispersion, reducing the graphene oxide to reduced graphene oxide by hydrothermal reduction method, and freeze-drying to obtain reduced graphene oxide powder; and (b) adding the reduced graphene oxide powder to gold cluster solution protected by a thiol ligand, adding ultrapure water, ultrasonically dispersing to obtain a mixed solution, loading the mixed solution onto the base film by vacuum suction filtration, washing, to obtain the final product, where the ratio of reduced graphene oxide to gold cluster is 5-10 mg:5-20 mu mol. USE - The method is useful for preparing gold cluster/graphene composite catalytic membrane. ADVANTAGE - The method has simple operation, produces product with large gold cluster load, high catalytic activity, easily recyclable and achieves the construction of high-efficiency catalytic membrane.
