摘　　要：随着全社会环境意识的增强,汽车尾气污染问题引起人们的广泛关注。采用三效汽车尾气净化催化剂能有效解决目前汽车尾气的污染问题。以堇青石蜂窝陶瓷为载体,活性氧化铝为涂层,涂载贵金属铂、铑、钯的三效汽车尾气净化催化剂已发展成熟,并获得广泛应用。介绍了汽车尾气净化催化剂的产生,阐述了汽车尾气净化催化剂回收技术的发展现状。Today we have focused on the car exhaust pollution problem with the stronger environmental consciousness The three-way automotive exhaust catalysts can be used to solve the vehicle exhaust pollution effectively. The three-way automotive exhaust catalyst which was carried by cordierite honeycomb, covered by activated alumina and precious metals （platinum,rhodium and palladium） has been developed. This paper expatiate the generation of the automotive exhaust catalysts and the status quo on recycling technology for automotive exhaust catalysts.
