Abstract

We report a facile and simple way to synthesize graphene@TiO2 nanocomposites with controlled crystal facets by a one-pot hydrothermal process. By controlling the concentrations of the starting materials and reaction times, graphene@TiO2 nanocomposites with various exposed crystal facets can be obtained. The surface states and the growth process of graphene@TiO2 nanocomposites have been studied. Owing to the exposed high-reactive crystal facets and high dispersities of TiO2 nanocrystals on graphene surfaces, the as-prepared sample exhibited enhanced photocatalytic activities over graphene@P25 nanocomposites.
