超声辅助La-TiO_2/膨胀珍珠岩的吸附与光催化性能
Adsorption and photocatalytic properties of La-TiO2/EP with ultrasonic wave assistance
摘要
Abstract
Floating La-TiO2/EP photocatalyst was prepared by impregnation method with expanded perlite（EP） as support and tetrabutyl titanate as precursor.The crystalphase and morphology of samples were characterized by X-ray diffraction（XRD）.Adsorption and photocatalytic performance of the La-TiO2/EP catalysts were evaluated by degradation of octane on water with the ultrasonic wave assistance.The experimental results indicate that the 5%La-TiO2/EP catalyst using the expanded perlite of 20~40 mesh as support and calcinated at 500 ℃ for 2 h has the best activity.The adsorption and migration of octane in catalyst surface is promoted by the ultrasonic wave,11.08% of octane is additionally removed with the help of ultrasonic wave.关键词
