At present, with the rapid development of nanoscience, nanotubes have become an important part of nanomaterials. As a new type of multifunctional semiconductor nanotube material, the self-ordered TiO 2 nanotube arrays (TNTs) have excellent optical and electrical properties, and they have a very wide application prospects in modern industrial fields. By using the method of anodic oxidation, the specific influence of reaction temperature on the microstructure and electrochemical properties of TNTs under the condition of acid system was investigated by the way of controlling variables. The results show that the lengths of TNTs and the thickness of the barrier film decrease with increasing temperature, and which is opposite in the radius and tube wall thickness. Additionally, in electrochemical properties of TNTs, the equivalent electrochemical impedance and crystallinity usually decrease with increasing of the temperature.
