摘要

In this paper we prepared titanium nanotube arrays in ethylene glycol organic electrolyte which contains ammonium fluoride through anodic oxidation method. We found that the preparation of the structure and morphology of TiO_2 nanotube arrays can be controlled by changing the preparation parameters. While the oxidation voltage is the main factor that controls the diameter of nanotubes, the length of nanotubes is mainly depending on the oxidation time, and the crystal type is closely related to the annealing temperature. Its photo-degradation rate of methylene blue can reach to 92% which is almost two times than the titania(P25).
