研究了Cu、Mn复合氧化物及其负载型An催化剂的物相结构、表面形貌、体相及表面的化学组成，考察了它们对CO氧化的催化活性及在200℃下进行氧化处理的效果．结果表明：Au和Ce加入Cu、Mn复合氧化物中，可提高其对CO氧化的催化活性；对催化剂进行氧化处理后，催化活性有所增加，表明对CO氧化的活性与晶格氧的数量有关；用浸渍法、涂层法所制备的催化剂其活性小于用共沉淀法制备的催化剂．
The phase structure, surface morphology, bulk phase and surface chemical composition of Cu, Mn composite oxides and their supported An catalysts were investigated. Their catalytic activities for CO oxidation and their effects of oxidation treatment at 200 ℃ were investigated . The results showed that adding Au and Ce to Cu and Mn composite oxides could increase their catalytic activity for CO oxidation. After the catalyst was oxidized, the catalytic activity increased, indicating that the activity of CO oxidation and the quantity of lattice oxygen ; With impregnation method, the catalyst prepared by the coating method is less active than the coprecipitation catalyst prepared.
