摘要
Abstract
Titania nanowire arrays were synthesized in highly ordered porous anodic alumina template by Sol-gel electrophoretic method.The samples were characterized by SEM and XRD. The photocatalytic properties of Nd~(3+)/TiO_2，F~-/ TiO_2 and Nd~(3+)/F~-/TiO_2 nanowire arrays were characterized by degradation of methyl orange solution. The results show that Nd~(3+)/F~-/TiO_2 nanowire arrays exhibit higher photocatalytic activity than that of Nd~(3+)/TiO_2 and F~-/ TiO_2 nanowire arrays. For Nd~(3+)/F~-/TiO_2 nanowire arrays，the degradation rate of methyl orange exceeds 90% after 1 h irradiation. At the same time，the absorption wavelength of TiO_2 film shifts red with the addition of impurity ions, indicating that the nanowire arrays exhibit some photocatalytic activity in visible spectrum.关键词
