Progress on photocatalytic degradation of organic pollutants by
Abstract
Graphene ? a New kind of carbon nano-materials with a large specific surface area Then Excellent electrical conductivity. When I is incorporated into TiO2Semiconductor to form a composite materials , TiO2 Photocatalytic performance could do greatly enhanced and , 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 inTiO2 surface for Organic pollutions In certain Extent . In This Review , Preparation methods of graphene /tio2 composite Nanomaterials and their application in Photocatalyticdegradation of organic pollutants are reviewed. and , mechanism to Photocatalytic enhancement by Graphene/tio2 Composites is also analyzed. Finally , The future prospecton the trends of Graphene/tio2 composite photocatalyst is also given .References
