摘 要：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>0.76）,（2） rare-earth metals（especially Pr） modified ceria,（3） transition metals（especially Mn and Cu） modified ceria, and（4） Ag/CeO 2. 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.
