摘要：

Pure brookite films were deposited from a brookite dispersion obtained by peptizing a mixture brookite-rutile prepared by then-nolysis of TiCl4 in a HCl solution. The films were characterised by X-ray diffraction and Raman spectroscopy. The photoactivity of the samples was tested by using the photo-oxidation of 2-propanol in gas-solid regime as a probe reaction. The brookite films efficiently degraded 2-propanol under UV illumination. (c) 2006 Elsevier B.V. All rights reserved.
