Vertically Aligned Binder-Free TiO2 Nanotube Arrays Doped with Fe, S and Fe-S for Li-ion Batteries
Vertically aligned Fe, S, and Fe-S doped anatase TiO2 nanotube arrays are prepared by an
electrochemical anodization process using an organic electrolyte in which lactic acid is
added as an additive. In the electrolyte, highly ordered TiO2 nanotube layers with greater
thickness of 12 μm, inner diameter of approx. 90 nm and outer diameter of approx. 170 nm
are successfully obtained. Doping of Fe, S, and Fe-S via simple wet impregnation method
substituted Ti and O sites with Fe and S, which leads to enhance the rate performance at …
