Abstract

The invention discloses a titanium dioxide / graphene nanocomposite, and a normal-temperature preparation method and application thereof. According to the invention, a titanium source and graphite oxide are used as starting raw materials, an organic solvent is used as a reaction solvent, and the nanocomposite formed by compounding of titanium dioxide nanometer rods and graphene is obtained through normal temperature reduction and hydrolysis; and in the nanocomposite, graphene accounts for 1 to 30 wt%, with the rest being titanium dioxide. The preparation method provided by the invention has the advantages of simple process, easy preparation, mild reaction conditions, etc. In the prepared nanocomposite, titanium oxide is uniformly distributed on the surface of graphene, so the nanocomposite can be perfectly applied to the field of photocatalysis of photoelectric materials.
