Developments in ceria-based soot oxidation catalysts, especially during the last decade, are reviewed. Based on the com-parisons of the activity, durability and cost-efficiency of different soot oxidation catalysts, four kinds of applicable ceria-based cata-lysts have been screened out, which are: (1) CexZr1–xO2 catalyst with high cerium content (x>0.76), (2) rare-earth metals (especially Pr) modified ceria, (3) transition metals (especially Mn and Cu) modified ceria, and (4) Ag/CeO2. Moreover, a general review of recent developments on the morphology-controlled ceria-based catalysts, as well as that on the soot oxidation mechanisms over different ceria-based catalysts, is also presented.
