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。
Abstract
A series of Cu-Mn-Ce-Zr catalyst s were prepared by co-precipitation in this study. The activities of catalyst s for the moval effect of benzene were evaluated by a normal pressure gas flowing inst rument . According to the breakthrough curve and XRD spect rum , the surface characteristics of catalyst s were analysed. The result shows that CeO2 and ZrO2 can improve the catalytic activities of Cu-Mn-O catalysts.
