摘要
催化净化是解决汽车尾气污染的一项关键技术 ,本文以CO氧化为探针反应 ,考察了镧对混合型贵金属催化剂反应活性、耐热性能的影响 ,并探讨了镧的作用机理。结果表明
Catalytic technology is one of the major methods to purify automobile exhaust gas.In this work,the activity and heat-resistant quality of noble metals catalyst were investigated by CO oxidation,and the role of La 2O 3 in the catalyst was discussed by activity energy and TPD.It has been shown that lanthanum is a nice promoter of the noble metals catalyst for automobile exhaust.
