Abstract TiO 2 nanotubes prepared by using a hydrothermal process were firstly coated with silver nanoparticles as the anode materials for lithium–ion batteries by the traditional silver mirror reaction. The physical properties of the as-synthesized samples were investigated by X-ray diffraction and transmission electron microscopic. The as-prepared samples were used as negative materials for lithium–ion battery, whose charge–discharge properties, cyclic voltammetry, electrochemical impedance spectroscopy and cycle performance were examined in detail. The results showed that the Ag additive decreased the polarization of anode, and marvelously improved the high-rate discharge capacity and cycling stability of TiO 2 nanotubes.

• Hierarchically ordered macro-mesoporous TiO₂-graphene composite films: improved mass transfer, reduced charge recombination, and their enhanced photocatalytic activities. (2011, unknown): “solid-state interface layer resistance and the chargetransfer resistance on the surface.(5,26,29) Therefore, the electron-accepting and electron-transporting properties of graphene in the composite films could indeed suppress the charge recombination and improve their photocatalytic activities.”
