摘　　要：采用共沉淀法制备了稀土催化剂,并考察了沉淀剂种类、制备方法、煅烧温度以及稀土对催化效果的影响。试验结果表明:以Na2CO3为沉淀剂,添加稀土Sm,于300℃煅烧4h制得的稀土催化荆能够在0℃左右将CO完全氧 化。Rare-earth catalyst has been prepared by co-precipitation method. In this paper,the influence of the types of precipitating agent,preparing methods,calcination temperature and the kinds of rare-earth were studied. It was found that the sample prepared by co-precipitation method with Na2CO3 as precipitating agent,calcined at 300℃ in air for 4h can oxidize CO to CO2 at about 0℃ completely.
