چکیده انگلیسی
Anatase
TiO2 sols were synthesized under mild conditions (i.e. 75 °C and ambient pressure) by hydrolysis of titanium-
n-butoxide in abundant acidic aqueous solution and subsequent reflux to enhance crystallization. The influences of various acidities on crystallinity, morphology, and size of the obtained
TiO2 sol particles were investigated. At room temperature and in ambient atmosphere, crystalline
TiO2 thin films were deposited on quartz glass slides from the as-prepared
TiO2 sol by a dip-coating method.
TiO2 films on substrates could be thickened by means of consecutive dip-coating processes. The photocatalytic activities of the
TiO2 thin films were assessed by the degradation of X-3B in aqueous solution under aerated conditions. The preparation process of photocatalytic
TiO2 thin films was quite simple and a low-temperature route.
