NOVELTY - Preparation of bismuth vanadium oxide/tungsten trioxide/reduced graphene oxide ternary nanocomposite material comprises taking graphene as substrate, uniformly loading nano-bismuth vanadate and nano-tungsten trioxide on the graphene surface; uniformly distributing nano-tungsten trioxide on the graphene surface; and paving the nano-bismuth vanadate on graphene or attached to tungsten trioxide between nanorods. USE - Method for preparing BiVO4/WO3/rGO ternary nanocomposite material (claimed). ADVANTAGE - The method is simple and easy to operate. DETAILED DESCRIPTION - Preparation of bismuth vanadium oxide (BiVO4)/tungsten trioxide (WO3)/reduced graphene oxide (rGO) ternary nanocomposite material comprises: (A) taking graphene as substrate, uniformly loading nano-bismuth vanadate and nano-tungsten trioxide on the graphene surface, where weight ratio of nano-tungsten trioxide to nano-bismuth vanadate is 4:1-1:4, the total mass of the nanocomposite material is 1-10 mass%, and diameter of nanorod nano-tungsten trioxide is not greater than 5 nm; (B) uniformly distributing nano-tungsten trioxide on the graphene surface; and (C) paving the nano-bismuth vanadate on graphene or attached to tungsten trioxide between nanorods, where the bismuth nanosheet size structure is 100-200 nm.
