Abstract

Composites of TiO2-B nanorods and reduced graphene oxide (RGO) were prepared through a simple two-step hydrothermal process followed by subsequent heat treatment in argon. The obtained TiO2-B nanorods had a small size (∼10 nm diameter of the nanorod) and a uniform morphology. Importantly, the synergistic effect of RGO nanosheets and nanostructured TiO2-B leads to electrodes composed of the TiO2-B-RGO nanocomposites which exhibit excellent cycling stability and rate capability (260 mA h g(-1) at 1 C and 200 mA h g(-1) at 2 C after 300 cycles and 140 mA h g(-1) at 20 C).
