Graphene-titanium dioxide (TiO2) hybrid nanomaterials have received much attention due to their high potential in enhancing the photocatalytic efficiency. In the hybrid system, graphene acts as an electron acceptor to ensure the fast charge transfer to the current collector. Three-dimensional (3D) graphene in this context represents a new format of graphene material to further enhance the photocatalytic efficiency. 3D graphene has been shown to be a good candidate for making hybrid materials due to its outstanding properties, including increased surface area, multiple conductivity pathways, absence of intersheet contact resistance, reduced agglomeration of two-dimensional (2D) graphene sheets, and ease of handling and control. The examples included in this chapter have shown the high potential of 3D graphene in developing high-efficiency photocatalysts based on 3D graphene-TiO2 hybrid nanomaterials.
