摘要
Herein, we firstly used hydrothermal-assisted liquid phase deposition (HT-LPD) approach to prepare anatase titania nanocrystals, with gamma-Al(2)O(3) as the fluorion scavenger. The as-prepared products were characterized by X-ray powder diffraction, UV-vis diffuse reflectance spectrometer, and transmission electron microscope. Compared with titania nanocrystal prepared by LPD method, titania nanocrystals prepared by HT-LPD method exhibited better photocatalytic activity, especially the nanocrystal prepared by HT-LPD method at 200 degrees C for 3 h. The possible reason for the enhanced photocatalytic activity was investigated. (C) 2010 Elsevier B.V. All rights reserved.
