Abstract: TiO2-graphene aerogel (TiO2-GA) 3D hybrids were directly assembled via a one-pot hydrothermal process followed by freeze-drying without using any structure-directing agent. The hybrids with a hierarchical structure exhibited large surface area (S-BET = 283.6 m(2) g(-1)) and high pore volume (V-p = 0.278 cm(3)g(-1)), in which the ultradispersed TiO2 nanoparticles were in a single crystal phase of anatase. When used as the anodes for lithiuni ion battery, the TiO2-GA hybrids exhibited higher reversible capacity, more stable cycling performance and better rate-capability than TiO2 ascribed to the Unique 3D nanoporous structure and the synergistit interaction of GA and TiO2.
