| 摘 要： | 采用聚丙烯酰胺溶胶-凝胶法制备了A位掺杂(Cu、Ce)LaSrCoO4复合氧化物催化剂,考察了它们对CO和C3H8的催化氧化活性,并运用XRD,TPR和TPD等手段对催化剂进行了表征。结果表明,不同稀土掺杂对LaSrCoO4复合氧化物的CO和C3H8氧化活性的影响不同,Cu掺杂能增加Co3+、化学吸附氧和晶格氧的数量,提高复合氧化物的活性,而Ce则相反。

| Abstract: | A-site doped LaSrCoO4 mixed oxides were prepared by polyacrylamid sol-gel method.The samples were characterized by XRD,TPR and TPD.Results showed that different influence of Cu and Ce on activity of LaSrCoO4 for CO and C3H8 oxidation were observed.La0.6 Cu0.4SrCoO4 catalyst has better activity for CO and C3H8 oxidation comparing with LaSrCoO4 catalyst.La0.6Cu0.4SrCoO4 catalyst can increase the amount of Co3+,chemisorbed oxygen and lattice oxygen. |
