Facile synthesis of graphene-titanium dioxide nanocomposites as anode materials for Na-ion batteries

Graphene-titanium dioxide (TiO2) composites were prepared via one-step vapor reaction process. TiO2 nanoparticles obtained from the vapor reaction and loaded on graphene. Graphene-TiO2 was used as Na-ion battery anode materials with a stable specific capacity of 102 mAhg−1 at a current density of 0.1 A/g.209
