饼状分层结构CeO2负载Ru催化剂催化氧化1,2-二氯乙烷性能研究
Study on the Performance of Ru Catalyst Supported on Disc-shaped Layered CeO2 for the Oxidation of 1,2-Dichloroethane
摘要
Abstract
CeO2 materials with different morphologies were synthesized by solvothermal method,direct calcination method and aqueous precipitation method,and 1 wt%Ru was loaded by impregnation to prepare Ru/CeO2 catalysts with different morphologies.The Ru/CeO2 catalysts with different morphologies were used to catalyze the oxidation of 1,2-dichloroethane(1,2-DCE)under the conditions of 1 000 ppm 1,2-DCE,oxygen content of 10%,and space velocity(WHSV)of 30 000 mL/(g·h).The order of catalytic performance from high to low was Ru/CeO2-r(disc-shaped)>Ru/CeO2-d(block-shaped)>Ru/CeO2-s(sheet-shaped).Ru/CeO2-r achieved a degradation rate of 90%for 1,2-DCE at 331℃,showing the best catalytic performance.The characterization by scanning electron microscopy(SEM),X-ray diffraction(XRD),Raman spectroscopy and NH3-TPD confirmed that Ru/CeO2-r had smaller particle size,higher OV and Ru-O-Ce structure content as well as stronger acidity,which promoted the catalytic oxidation of 1,2-DCE.The experimental results provide a research basis for the catalytic treatment of industrial chlorinated pollutants.关键词
