β2-SiW11/TiO2光催化剂的制备及光催化性能
Preparation and photocatalytic performance of photocatalyst β2-SiW11/TiO2
摘要
Abstract
The composite photocatalyst β2-SiW11/TiO2 was prepared by impregnating silicotungstate on ti⁃tanium dioxide by impregnation method, β2-K8SiW11O39·xH2O as active component. Then catalyst β2-SiW11/TiO2 were characterized by infrared spectroscopy (IR), UV spectroscopy, thermal gravimetric (TG), X-ray photoelec⁃tron spectroscopy (XPS), X-ray diffraction (XRD) and scanning electron microscopy (SEM). Meanwhile, the pho⁃tocatalytic activity of the catalyst was assessed using the photocatalytic degradation of methylene blue, a mod⁃el pol utant, as a probe. The influences of the β2-SiW11/TiO2 dosage and the solution pH on the catalyst activity were examined. The results showed that compared with TiO2 and β2-K8SiW11O39·xH2O, β2-SiW11/TiO2 had the advantage, which played a synergistic effect. The degradation rate of methylene blue was 82.53%.关键词
