Herein we obtained a chemically bonded TiO2 (P25)-graphene nanocomposite photocatalyst

with graphene oxide and P25, using a facile one-step hydrothermal method. During the hydrothermal reaction,

both of the reduction of graphene oxide and loading of P25 were achieved. The as-prepared P25-graphene

photocatalyst possessed great adsorptivity of dyes, extended light absorption range, and efficient charge

separation properties simultaneously, which was rarely reported in other TiO2-carbon photocatalysts. Hence, in

the photodegradation of methylene blue, a significant enhancement in the reaction rate was observed with P25-

graphene, compared to the bare P25 and P25-CNTs with the same carbon content. Overall, this work could provide

new insights into the fabrication of a TiO2-carbon composite as high performance photocatalysts and facilitate

their application in the environmental protection issues.
