| 中文摘要: |
| 为了改善环境质量，我国在2020年7月1日对轻型汽车排放的颗粒物进行限制。为了满足法规要求，汽油机颗粒捕集催化剂技术被大量应用于汽油车后处理中。基于2007年以来50篇文献的分析，本文总结了汽油机颗粒捕集催化剂在系统布局、铂族金属种类和浓度、涂层分布、背压、颗粒物捕集、积碳再生、灰分容量以及辅助气态污染物净化方面最新研究成果；展望了汽油机颗粒捕集催化剂未来应用发展趋势。 |
| 英文摘要: |
| To improve ambient air quality, China have adopted regulations setting stringent limits on vehicular tailpipe emissions of particulates on July 1, 2020. To meet these regulations, the catalyzed gasoline particulate filters have heavily been applied to gasoline exhaust after-treatment. Based on the analysis of 50 literatures since 2007, this review summarizes representative studies on the system layouts, platinum group metal concentrations and species, washcoat distribution, back pressure, particulates filtration efficiency, soot regeneration, ash storage capacity and auxiliary gaseous pollutant purification, in the field of catalyzed gasoline particulate filters. The future application and developments are prospected. |
