摘要
汽车尾气的排放破坏了大气的臭氧层,造成了环境污染,对汽车尾气的净化处理势在必行。开发新型、高效、稳定且环境友好的催化剂成为尾气净化领或的研究热点,文中综述了国内外柴油车尾气处理氮氧化物催化剂的工艺技术,展望了其发展方向。
The vehicle exhaust emission damaged atmospheric ozone layer,and caused environmental pollution,so it is imperativeto make purification treatment to vehicle exhaust. The development of novel,highly efficient,stable and environmentally friendlycatalysts have become the research hotspot in the exhaust purification field. This paper summarized the process technologies at homeand abroad for catalysts for treating NOx in diesel vehicle exhaust,and expected their development direction.
