摘要
The TiO 2 powder was prepared by a stearic acid gel method. XRD characterization indicated that the crystal form was anatase. The grain size, given out by Sherrer formula, is 19 nm. With polystyrene dissolved in toluene as binder, TiO 2 adhered to the glassfibre substrate. By this method, the powder was immobilized and the crystal form, grain size and photocatalysis activities were well maintained. Photocatalysis degradation properties were investigated by putting the TiO 2 immobilization film in the methyl orange aqueous system. The results indicated that the differences of degradation rate between the TiO 2 immobilization film and powder were not obvious, which made waste water treatment using photocatalysis degradation technique possible in the practical application.
