Abstract: Nitrogen-doped TiO₂ nanotube-like arrays electrodes were prepared by anodic oxidation and then followed by being treated in N² flow at 500 and 600℃.The samples were characterized by environmental scanning electron microscope（ESEM）,X-ray diffraction（XRD）,X-ray photoelectron spectrum（XPS） and UV-vis spectrum.The results showed successful incorporation of nitrogen into the TiO₂ nanotube.Enhanced photoelectrocatalytic activity in visible light region was observed owing to nitrogen doping.By comparison,the sample being treated in N² flow at 500℃ exhibited the best photoelectrocatalytic activity.
