TiO₂ graphene composite was obtained by a one step hydrothermal method,using graphite oxide and commercial TiO₂ as precursors.The morphology and structure of the composite were examined by scanning electron microscopy,transition electron microscopy,X-ray diffraction,N₂ adsorption-desorption and Raman spectrum.The as-prepared TiO₂-graphene photocatalyst possessed great adsorptivity of dyes,extended light absorption range,and efficient charge separation properties.Hence,in the photodegradation of methylene blue,a significant enhancement in efficiency was observed with TiO₂-graphene compared to the neat TiO₂.
