▎ 摘　　要

NOVELTY - Tungsten oxide (WO3) doped with zeolitic imidazolate framework (ZIF-67) visible light catalytic composite material loaded on graphene oxide (GO) is obtained by uniformly dispersing WO3 @ZIF-67 composite powder on the surface of the graphene oxide (GO) film and firmly combining with the film; where, in the WO3@ZIF-67 composite powder, the WO3 powder is uniformly wrapped by ZIF-67 crystals. USE - WO3 doped with ZIF-67 visible light catalytic composite material used to photocatalysis antibacterial and pollutant purification (claimed). ADVANTAGE - The composite material exhibits excellent performance of killing bacteria and mineralizes pollutant, where tungsten WO3 has high photo-catalytic activity, high stability safe and non-toxic but has low utilization rate of the sunlight low quantum efficiency. The photo-catalytic material composite can expand the visible light response range and effectively separates the photo-generated carrier.
