Crystallinity and photocatalytic activity of liquid phase deposited TiO2 films

Issue Title: Special Issue: Symposium on Functional Ceramic Materials and Thin Films of ICMAT 2005: Part I July 2006 Anatase TiO^sub 2^ films were deposited on glass substrates at 50 and 200^sup ^C to investigate the effect of growth temperature on the photocatalytic acitivity of the films. It was observed that the films grown at 200^sup ^C were composed of columnar crystallites and were more porous than the films grown at 50^sup ^C which had more compact structures. Also, the film crystallinity increased from 75 to 90% if the higher growth temperature was used. Despite the higher crystallinity, it was observed that for crystallinities between 60 and 90%, the photocatalytic behavior of the films was more significantly affected by changes in the surface area.[PUBLICATION ABSTRACT]
