摘要
综述了世界汽车尾气催化技术现状 ,指出钙钛矿型催化剂、贫况氮氧化物 (NOx)催化剂、柴油机尾气催化剂是目前人们的研究热点 ,特别是柴油机汽车尾气催化剂由于柴油发动机的燃油经济性、可靠性、耐久性正孕育着一个巨大的潜在市场。并对未来汽车尾气催化技术进行了展望。
As automotive emission legislation is tightening world wide,catalytic technologies for automotive exhaust have been developing rapidly.In this paper,the present situation of catalytic technologies for automotive exhaust are reviewed.It is pointed out that perovskite ABO 3 catalysts,lean burn NO x catalysts and diesel engine emission catalysts all have attracted much attention in the current global research field of automotive catalysts.In particular,the diesel engine emission catalysts are breeding a huge potential commercial market because of the economical efficiency,reliability and durability of the diesel engine.Also the future automotive exhaust catalytic technologies are prospected.
