Abstract

TiO2 nanotube arrays were made on the titanium foil by the method of anodic oxidation. Large-area crystallized free-standing TiO2 nanotube arrays were fabricated by a two-step anodization, and then crystallized by different heat-treatment processes. The morphology and structure of the TiO2 nanotube arrays were characterized by scanning electron microscope (SEM) and X-ray diffraction (XRD). The results show that the diameter of the TiO2 nanotube at the voltage range of 50V~65V was about 100nm. Anatase phase is the unique phase observed in free-standing TiO2 arrays annealed at the temperature of 400°C~610°C. However, crystallographic orientation of anatase phase is influenced by the annealing temperature.
