Ce改性Fe2O3催化剂对CO催化氧化的影响
Effect of Ce addition on Fe2O3 catalyst towards CO catalytic oxidation
摘要
Abstract
A series of iron-ceria oxide catalysts were prepared by co-precipitation method and the effects of Ce adding into Fe2O3 on CO catalytic oxidation activity were investigated.Activity result shows that the addition of Ce increases the CO catalytic activity significantly,which can attain more than 90％ CO conversion at ambient temperature and atomospheric pressure.Higher surface area and better redox ability than those of pure Fe2O3,and the formation of iron-ceria solid solution in the catalyst may be responsible for the increased catalytic activity.Additionally,different iron precursor has great influence on the CO catalytic oxidation.Sample that was prepared by using FeC13 as iron precursor shows the best catalytic performance.关键词
