用共沉淀法合成了铜-锰-铈-锆复合氧化物系列催化剂,用常压气体流动评价装置考查了其对苯蒸气的催化活性,并根据穿透曲线、XRD衍射对催化剂表面性质进行了分析。结果表明:CeO2和ZrO2对以铜、锰氧化物催化剂的催化活性有促进作用。
A series of Cu Mn Ce Zr catalysts were prepared by co precipitation in this study. The activities of catalysts for the moval effect of benzene were evaluated by a normal pressure gas flowing instrument. According to the breakthrough curve and XRD spectrum, the surface characteristics of catalysts were analysed. The result shows that CeO 2 and ZrO 2 can improve the catalytic activities of Cu Mn O catalysts.
