Abstract

One-dimensional nanostructured metal oxide can be formed through an anodic oxidation, which is a typical technique of metal surface treatment. Studies on $TiO_2$ nanotubes have been widely carried out with increasing interests in $TiO_2$, which has an excellent functionality among various metal oxides. The present article reviews the principles of formation of $TiO_2$ nanotubes, which have been studied so far. In particular, the article discussed the equilibrium relationship between the oxide formation and etching, which is a key parameter of $TiO_2$ nanotube growth, and the formation of the porous structure. Furthermore, morphological considerations of $TiO_2$ nanotubes according to electrolyte conditions will be explained to the researchers who will study the application of $TiO_2$ nanotubes formed through the anodic oxidation in the future.
