摘要：

Self-organized Sn-doped TiO2 nanotubes (nts) were fabricated for the first time, by anodization of co-sputtered Ti and Sn thin films. This nanostructured material was characterized by scanning electron microscopy, energy dispersive X-ray spectroscopy, X-ray diffraction, UV-vis spectroscopy and transmission electron microscopy. Due to their remarkable properties, Sn-doped TiO(2)nts can find potential applications in Li-ion microbatteries, photovoltaics, and catalysis. Particularly, the electrochemical performance as an anode material for Li-ion microbatteries was evaluated in Li test cells. With current density of 70 mu A cm(-2) (1C) and cut-off potential of 1V, Sn-doped TiO(2)nts showed improved performance compared to simple TiO(2)nts, and differential capacity plots revealed that the material undergoes full electrochemical reaction as a Rutile-type TiO2.
