| 摘 要： | 以非离子型表面活性剂Triton X-100为模板剂,用水热法制备了介孔TiO2,探究了不同反应条件对样品光催化活性的影响,对制得的样品进行了XRD、SEM、N2吸附-解吸及差热-热重等表征.结果表明,所得样品为窄孔道分布,最可几孔径为3.4 nm,当水热温度为120℃,焙烧温度为400℃,Ti(SO4)2∶OP∶C2H5OH为4∶1∶40(摩尔比)时,所制得样品的可见光催化活性最好.

| Abstract: | Mesoporous TiO2 was synthesized by hydrothermal method using non-ionic surfactant Triton X-100(OP) as the template.The samples were characterized by X-ray powder diffraction(XRD),N2 adsorption-desorption,Scanning Electron Microscope(SEM),Fourier Transform Infrared Spectroscopy(FT-IR) and Thermal analyses(TG-DTA) techniques.Effects of different reaction conditions on the visible-light photocatalytic performance were discussed.The samples showed a narrow pore size and the distributing pore diameter of 3.4nm.W... |
