"Proceedings of the workshop Recent advances in photochemistry, electrochemistry and photocatalysis" . "P(1M0577)" . "This paper deals with the preparation and characterization of thin transparent films of TiO2 with particular interest to the effect of film thickness (repeated layer deposition) and to the relation between crystallinity, photoactivity and surface hydrophility. TiO2 layers were prepared by sol-gel method from titanium(IV) iso?propoxide, isopropyl alcohol and acetylacetone were used as solvents and hydrochloric acid as a catalyst. Final calcination was at 500 \u00B0C for 2 hours. Characterization was performed using XRD, UV/VIS spectroscopy and SEM. Photoactivity was measured using two dyes: anionic acid orange 7 and cationic methylene blue." . . "Novotn\u00E1, Petra" .
