The possibilities of GPF Surface modification in the aspect of micro-contaminants removal

Abstract

The European Union Fit For 55 program plans to cease the production and sales of vehicles with the internal combustion engines in 2035, although fuel powered vehicles will remain on the road for many more years to come.The micro-contaminants (MC) in gasoline exhaust such as Polycyclic Aromatic Hydrocarbons (PAHs) and their derivatives, ions, metals and metalloids are highly toxic and carcinogenic.The gasoline particulate filter (GPF) is the most commonly used solution for solid particulate emission control. Studies show that use of the metals such as Cu, Co, Fe, Ni or Mn improves oxidation of MCs. The aim of this study is to review the knowledge about the gasoline particulate filters, their mechanisms of pollutants removal and to highlight the probable insufficiency in avoiding of hazardous micro-contaminants emission. The work also reviews some more important and relevant publications to the subject.
