| 英文摘要 | TiO2/MCM-41. composites with various titania content were prepared by loading titania into the mesopores of MCM-41 molecular sieves via the sol-gel method. TiO2/MCM-41 composites were characterized by Xray diffraction (XRD), N-2 adsorption, ultraviolet-visible (UV-Vis) absorption spectroscopy and transmission electron microscopy (TEM) techniques. The titania crystalline phase was anatase. The BET surface area and pore volume of the composites decreased with the increase of titania loading (mass ratio of TiO2 to MCM-41. in the composite). The average crystal size of these titania particles increased as the titania loading increased. The photocatalytic activities of TiO2/MCM-41 composites were evaluated by the photocatalytic degradation of Rhodamine B. The degradation of Rhodamine B followed first-order reaction kinetics. The composites showed higher photocatalytic activities than P-25 commercial pure titania nanoparticles. The photocatalytic activities of the composites depended on their adsorption abilities and the activity of titania loaded into the MCM-41 molecular sieves. |
