摘要：

Transparent nanocrystalline TiO2 thin films were deposited on soda lime glass (SLG) at a low temperature by a simple sol-gel dip-coating method. TiO2 sols were prepared from titanium alkoxide in acidic aqueous solutions and were subsequently refluxed at 80 degreesC for 8 h, leading to the formation of anatase crystallites. The as-deposited TiO2 films were heated at 115 degreesC for 15 min. The resulting films consisted of uniform spherical particles of about 20 nm in size and had excellent photoactivity for the degradation of ethanol. (C) 2004 Elsevier B.V. All rights reserved.
