Paper Title:
Photocatalytic Activities of Visible-Light-Driven TiO2 Films Codoped with Aluminum and Nitrogen
  Abstract

The titania films codoped by aluminum and nitrogen have been prepared by cathodic vacuum arc with titanium aluminum alloy target in an O2/N2 gas mixture. The films were characterized by X-ray diffraction (XRD), X-rayphotoelectron spectra (XPS) and ultraviolet-visible spectra (UV–vis). The results showed that all films annealled were crystalline anatase structure with a (101) preferential orientation, XPS revealed that Al and N were successfully doped into the lattice of TiO2. The optical properties of the films revealed that the spectrum response of the Al, N-codoped TiO2 films extended from the UV region to the visible region. The absorption of the Al, N-codoped TiO2 film in the visible region(>400 nm) was enhanced, compared with the pure TiO2 film and N-doped TiO2 film. The Al, N-codoped TiO2 film showed the best photocatalytic activities for the oxidative destruction of Acid Fuchsin (AF) under visible light irradiation.
