Abstract
Optically transparent, hydrophilic, porous titania and Zn-doped titania thin films were prepared by the sol–gel technique, using the non-ionic amphiphilic block copolymer Pluronic P123 as the template. The structure and optical properties of these films were characterized using SEM, XRD, UV-vis spectroscopy and BET surface area determinations. It was found that the addition of zinc to TiO2 increased its surface acidity and hydrophilicity, and hence the catalytic activity of mesoporous TiO2/ZnO (1–10 atom %) films in the decomposition of the xantene dye, Rhodamine B.
