摘要
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） CexZrl-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.
