摘　　要：With the enhancement of the people consciousness of environment protection, soot particulates(PM)elimination has drawn wide attention in recent years. Efficient after-treatment with well-designed catalysts is one of the best ways to eliminate soot particulates that come from diesel engines. Catalysts coated on the DPF(diesel particulate filter) are considered as the main factor to lower soot ignition temperature.Improvement of the structures of the catalysts is significantly important in order to achieve good catalytic performance and high stability. Based on the structures, soot combustion catalysts can be mainly divided into three types: particle-based catalysts, 3 DOM catalysts and nanoarray catalysts. This review mainly summarized recent advances in soot combustion catalysts with different designed micro-structures, each category is explained with critical assessment and several typical examples, aiming to guide the synthesis of advanced soot combustion catalysts.
