▎ 摘　　要

NOVELTY - Preparation of a polyaniline/titanium dioxide/graphene composite material involves taking titanium oxide and titanium tetrachloride as raw materials to prepare titanium dioxide/graphene composite material by a one-step hydrothermal method, then taking aniline as a raw material, and loading polyaniline oxidized by ammonium persulfate on the surface of the titanium dioxide/graphene composite material by electrostatic adsorption method, where the number of layers of the graphite oxide is 5-20 layers. USE - The method is useful for preparing polyaniline/titanium dioxide/graphene composite material, which is useful for photocatalytic desulfurization (claimed). ADVANTAGE - The coated polyaniline strengthens the connection between titanium dioxide and graphene, and forms conductive network with graphene, accelerates the rate of electron conduction, and improves the stability of the composite material. The graphene in the composite material increases the photoresponse range, improves the electron-hole separation rate, and enhances the photocatalytic ability. The titanium dioxide in the composite material is anatase type with more oxygen holes and has excellent catalytic ability.
