摘要
A novel class of Mania nanotubes (TNTs) have been prepared by ultrasonic assisted sol-hydrothermal method using tetrabutyl titanate and ethanol as the precursors. The physicochemical characteristics of the catalysts were investigated by transmission electron microscopy (TEM), X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) method, Differential Scanning Calorimeters-Thermogravimetric Analysis (Dsc-TG) and UV-vis absorption spectra. The photocatalytic activity of the products was evaluated in terms of reactive brilliant red X-3B in an aqueous solution under UV irradiation for 1 h. The results showed that the anatase nanotubes prepared by ultrasonic assisted sol-hydrothermal method exhibited excellent photocatalytic activity. The degradation rate of reactive brilliant X-3B could be up to 96%. The high degradation rate was attributed to the good crystalline pure-phase structure of nanotubes caused by ultrasound. Furthermore, the large surface areas also played an important role in the high degradation rate. (c) 2012 Elsevier Ltd. All rights reserved.
