Abstract

Nitrogen-doped TiO2 nanotube array was fabricated by an electrochemical anodic oxidation followed a wet process.XPS result indicates that the nitrogen atoms were doped into lattice of TiO2 nanotubes.The UV-Vis spectra show that the photoabsorption of N-doped TiO2 nanotube array film is enhanced in the visible light region.Compared with the TiO2 nanotube array film,the N-doped TiO2 nanotubes exhibite a higher photocatalytic activity which is evaluated by the decomposition rate of methyl orange using the tungsten-halogen lamp as light source.
