摘要：

Cr-doped TiO(2) nanotubes (Cr/TiO(2) NTs) with high photocatalytic activity were prepared by the combination of sol-gel process with hydrothermal treatment. XRD, TEM and UV-vis DRS techniques were employed for microstructural characterization. TEM images show that Cr/TiO(2) NTs are in good tubular structure and have diameter of about 10 nm. The Cr doping induces the shift of the absorption edge to the visible light range and the narrowing of the band gap. The photocatalytic experiment reveals that the photocatalytic performance of TiO(2) NTs can be improved by the doping of chromium ions.
