贫燃条件下汽车尾气净化催化剂的研究现状分析与展望

随着全球交通系统的发展，特别是贫燃发动机的设计和应用，汽车尾气中排放大量的NOX不仅严重地了环境，而且威胁到人类的身心健康，对净化汽车尾气中NOX的催化剂的研究成了国际上研究热点。本文综合了烃类选择性还原催化剂的研究状况以及它们的优缺点，分析各类催化剂的前景，并对新型载体剂提出展望。

Analysis and Prospect of the Research State of Purifying Automotive Exhaust under Lean- Burn Condition

With the development of global traffic system,especially,the design and application of engines in lean-burn condition, a great deal of NO X from automotive exhaust not only affect badly on the environment ,but also threat the health of human So the research of de-NO X catalysis for automotive exhaust control has become a popular subject The research state,the advantages and disadvantages of catalysts using HC to reduce nitrogen oxides kinds of catalysts,and prospect about new-type-carrier catalysts are discussed
