Microstructure Evolution of Hybrid TiO₂ Nanowire-Nanotube Structure Fabricated by Anodization

Abstract:

Hybrid TiO₂nanowire–nanotube structure was synthesized by a facile anodization on Ti substrate. To study the origin and evolution of TiO₂ nanotubes, the morphology of TiO₂ nanotubes was investigated. It was found that nanotubes corrode gradually into nanowires, and the critical time was about 8.5 h after the beginning of anodization. Uniform nanotubes were obtained by ultrasonic cleaning. It was demonstrated experimentally that the inner diameter of TiO₂ nanotube increased with the extension of anodization time, but the outer diameter of TiO₂ nanotubes, which were fabricated under different anodization time, was almost the same.
