Gas Phase Photocatalytic Oxidation of Trichloroethylene on Mesoporous TiO_2 Whiskers
|
Abstract:
Anatase TiO2 whiskers were synthesized by the reaction of TiO2-nH2O and K2CO3.The analytical results showed that the product was anatase with the sizes within microns, high ratio of area to mass and good uniformity in apertures.The photocatalytic activity of mesoporous TiO2 for the oxidation of trichloroethylene(TCE) in gas phase was studied under irradiation of UV lamp at 365 nm wavelength.Its degradation rate was up to 95% catalyzed by mesoporous TiO2, which was higher than that of Degussa P-25 TiO2(87%)....
