SDS对所制备的TiO2可见光催化活性的影响
Effects of SDS on Visible Light Photocatalytic Activities of the as-Prepared TiO2
摘要
Abstract
Titania photocatalysts(TPC) were successfully prepared by hydrolysis of TiCl4 in the presence of SDS.All of TPC were characterized by transmission electron microscopy(TEM),X-ray diffraction (XRD) analysis,UV-visible light spectra,and nitrogen adsorption/desorption.The results of photocatalytic activity test showed that all of TPC had better visible light photocatalytic activities than P25 for the photodegradation of methyl orange,and the visible light photocatalytic activity increased with the increase in the mole ratio of TiCl4 to SDS.SDS are helpful to regulate the distribution of high-energy oxo-bridging,so as to control visible light photocatalytic activities by regulating the intensity of interaction between particles.The exposed active facets is helpful to enhance its photocatalytic efficiency too.When the mole ratio of TiCl4 to SDS was 51.2,the methyl orange removal efficiency was up to 74.4% under visible light(35 W,common civilian illuminant) irradiation for 3 h.It would possess potential application prospect in self-cleaning interior building latex coating with photocatalysis.关键词
