摘　　要：如今,随着人们生活水平的不断提高,城市里汽车的数量正在以惊人的速度增长,但随之而来也有一些不容忽视的环境问题。但是由于发动机内部燃料的不完全燃烧,有许多燃烧不充分的产物如CO,HC,NOX等颗粒物,这些污染物对空气质量和人类健康都有非常不利的影响。文章给出了目前常用汽车尾气净化催化的机理,同时也讨论了汽车尾气净化催化剂及其载体的研究进展,催化转化器类型及其局限性,展望了汽车尾气净化催化剂的发展方向。Nowadays, with the improvement of people＇s living standard, the number of cars in the city is growing at a alarming rate, then some environmental problems also not allows to ignore. But because of incomplete combustion engine internal fuel, there are many inadequate combustion products such as CO,HC,NOx and other particles, these pollutants have a negative affect to air quality and human health. These paper presents the current commonly used in automobile exhaust purifying catalytic mechanism, also discuss the research progress of automobile exhaust purification catalyst and its carrier, catalytic converter type and its limitations, and also looking forward to the automobile exhaust purification catalyst development direction.
