摘要：
Graphene is a new kind of carbon nano-materials with a large specific surface area and excellent electrical conductivity. When it is incorporated into TiO2 semiconductor to form a composite materials, TiO2 photocatalytic performance could be greatly enhanced and the composite has extensive application prospect in the field of photocatalysis. Graphene in titanium dioxide/graphene nanocomposites can promote effectively separation of electron and hole, and enhance the absorption efficiency of TiO2 surface for organic pollutions in certain extent. In this review, the preparation methods of graphene/TiO2 composite nanomaterials and their application in photocatalytic degradation of organic pollutants are reviewed. And the mechanism of photocatalytic enhancement by graphene/TiO2 composites is also analyzed. Finally, the future prospect on the trends of graphene/TiO2 composite photocatalyst is also given. © All Right Reserved.
