Vertically oriented, highly ordered TiO2 nanotube arrays were fabricated via electrochemical anodization of high purity Ti sheet and Ti foil, which is increasing importance due to their impressing properties in a variety of applications including dye-sensitized solar cells, hydrogen generation by water photoelectrolysis, potocatalysis, and gas sensor. The well aligned TiO2 nanotube arrays by potentiostatic anodization of Ti foil (with 0.3mm thickness) were constructed. We have achieved the self-aligned high ordered nanotube arrays in aqueous electrolyte containing HF and ethylene glycol electrolyte containing NH4F. Depending on the fluoride ion mobile velocity, the resulting nanotubes arrays exhibit the different morphology. The elaborated electrolyte on the morphology of the self-organized nanotubes arrays was investigated. Thermal annealing on the anodized Ti induced crystalline formation, which is confirmed by Raman spectroscopy measurement.

Nanoscale engineering of regular structured materials is immensely demanded in various scientific areas. In this work, vertically oriented TiO2 nanotube arrays were grown by self-organizing electrochemical anodization. The effects of different fluoride ion concentrations (0.2 and 0.5 wt% NH4F) and different anodization times (2, 5, 10 and 20 h) on the morphology of nanotubes were systematically studied in an organic electrolyte (glycol). The growth mechanisms of amorphous and anatase TiO2 nanotubes were also studied. Under optimized conditions, we obtained TiO2 nanotubes with tube diameters of 70–160 nm and tube lengths of 6.5–45 μm. Serving as free-standing and binder-free electrodes, the kinetic, capacity, and stability performances of TiO2 nanotubes were tested as lithium-ion battery anodes. This work provides a facile strategy for constructing self-organized materials with optimized functionalities for applications.
