Ceria-based catalysts for soot oxidation: a review

Abstract Developments in ceria-based soot oxidation catalysts, especially during the last decade, are reviewed. Based on the comparisons of the activity, durability and cost-efficiency of different soot oxidation catalysts, four kinds of applicable ceria-based catalysts have been screened out, which are: (1) CexZr1–xO2 catalyst with high cerium content (x
