Carbon Coated N-Doping of TiO₂ Nanotube Films with Enhanced Visible-Light Photocatalytic Activity

Abstract:

Carbon coated N-doping of TiO₂ nanotube films were successfully prepared by a two-step process of anodization and gas thermal penetration. The morphologies and structures of composites were characterized by SEM, XRD, XPS and Raman spectroscopy analyses, respectively. The results show that graphitized carbon deposited on the surface of TiO₂NTs nanotubes under gas thermal penetration conditions, by which N atoms are incorporated into the lattice of TiO₂NTs through substituting the site of oxygen atoms. Such Carbon coated N-doping of TiO₂ nanotube films presents the enhance absorption in visible region. The photo catalytic tests show that the prepared films at 600°C reveal higher photocatalytic activity for splitting of water than other samples.
