Photocatalytic Enhancement in Methylene Blue Degradation of TiO2 Photocatalysts via Graphene Hybridization

摘要：

　　A facile route was demonstrated to obtain an efficient graphene-hybridized TiO2 photocatalyst.The photodegradation results of Methylene Blue over graphene hybridized with TiO2 showed that the photocatalytic activity could be significantly enhanced under UV light irradiation.The structure between TiO2 and graphene as well as its effect on the photocatalytic activity were systematically investigated.The mechanism of the enhanced photocatalytic activity is based to the high migration efficiency and the inhibition of recombination of photo-induced electron-hole pairs.The graphene hydridization is proven to be a promising approach to develop highly efficient and stable photocatalysts under UV light irradiation.
