Title: Characterization, properties and catalytic application of TiO{sub 2} nanotubes prepared by ultrasonic-assisted sol-hydrothermal method

Abstract

Graphical abstract: A novel class of titania 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, X-ray diffraction, Brunauer–Emmett–Teller 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 catalyst revealed an excellent photocatalytic activity. The degradation rate of reactive brilliant X-3B could be up to 96%. Display Omitted Highlights: ► TiO{sub 2} nanotubes were prepared by ultrasonic-assisted sol-hydrothermal method. ► TEM, HRTEM, XRD, and BET were used to study morphology and crystalline structure. ► FTIR, DSC-TG was used to investigate pyrolytic process and phase structure. ► UV–vis absorption spectra were used to evaluate the photocatalysis of catalysts. ► Dye degradation result showed that the catalyst had excellent photocatalytic activity. -- Abstract: A novel class of titania nanotubes (TNTs) have been prepared by ultrasonic assisted sol-hydrothermal method using tetrabutyl titanate and ethanol as the precursors.

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.« less
