NOVELTY - A flower-shaped nano tungsten oxide/graphene composite material has nano rod tip with flower petal-like structure and containing nanorods with diameter of 10-50 nm and length of 0.2-1 mu m. USE - Flower-shaped nano tungsten oxide/graphene composite material is used for preparing aniline gas-sensing element (claimed). ADVANTAGE - The flower-shaped nano tungsten oxide/graphene composite material is economically prepared within short period of time. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation of flower-shaped nano tungsten oxide/graphene composite material, which involves mixing soluble tungsten salt, sodium sulfate and graphene oxide solution, controlling pH value to 1-2, microwave heating mixture in reactor, natural cooling, separating, drying and calcining mixture; and (2) application of flower-shaped nano tungsten oxide/graphene composite material for preparing aniline gas-sensing element.
