N,F-codoped TiO2 nanowires were synthesized using titanium sulfate as a Ti precursor and isopropanol as a protective capping agent by a hydrothermal route. The obtained doped nanowires were characterized by XRD, SEM, TEM, HRTEM,SAED, XPS, porosimetry analysis and UV-vis diffuse reflectance spectroscopy. The synthesized N,F-codoped TiO2 nanowires calcined at 500 degrees C have TiO2 (B) and anatase phase and then are completely transformed to anatase phase after calcination at 600 degrees C. Photocatalytic activity measurements show that the N,F-codoped TiO2 nanowires calcined at 600 degrees C possess the best photocatalytic performance for the degradation of atrazine under UV and visible light irradiation in comparison with N,F-codoped TiO2 nanoparticles and N-doped TiO2 nanowires, which was attributed to the relatively more quantity of active {0 01} crystal facet due to the addition of F- and the synergistic effect of N and F doping.
