摘　　要：制备满足欧Ⅲ排放标准的摩托车尾气净化催化剂,制备需求的高性能稀土储氧材料和耐高温高比表面材料,在此基础上制备出密耦催化剂和三效催化剂。催化性能测定表明,密耦催化剂具有优异的低温活性和抗高温老化性能,三效催化剂具有优异的三效性能和抗高温老化性能,能满足欧Ⅲ排放标准的需求。The development of catalyst for the purification of exhaust from motorcycle for Euro Ⅲ compliance needs coupled catalyst and three-way catalyst soured from high-performance rare earth oxygenstorage materials and high performance heat-resistant surface materials. According to the results of the performance test for these catalysts, coupled catalyst has the characteristics of excellent low-temperature activity and aging resistance at high-temperature; the three-way catalyst has the features of excellent three-way performance and aging resistance at high-temperature, meeting the requirements of Euro Ⅲ standard.
