Graphene-titanium dioxide (TiO2) materials were prepared using titanium tetrachloride (TiCl4) and graphite oxides (GO) via a simple and continuous vapor reaction process. TiO2 nanoparticles obtained from the reaction assembled into clusters loading on graphene or attached onto graphene individually to form graphene-TiO2 nanocomposites. Graphene not only could enhance the nanocomposite electric conductivity but also is useful to improve the material porosity. The nanocomposites exhibited an enhanced performance for Na-ion battery anode with a specific capacity of 115 mAhg(-1) at a current of 1 A/g and a stable specific capacity of 102 mAhg(-1) at 0.1 A/g after 300 cycles.
