摘要：

Transparent anatase TiO2-based multilayered photocatalytic films on porous alumina and glass substrates were synthesized via a sol-gel process. All films had a sponge-like microstructure and a mean crystallite dimension of ca. 8 nm. The simple anaerobic decomposition of acetic acid reaction was used as the standard test system for evaluating the photocatalytic activity of the films. Doping with iron(III) impeded the photocatalytic activity. (C) 1998 Elsevier Science Ltd.
