| 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. |
