摘　　要：柴油车尾气排放的碳烟颗粒已经引起了严重的环境污染问题,必须加以净化处理。柴油车碳烟颗粒的低温燃烧离不开高活性的催化剂。针对柴油车排放的碳烟颗粒物后处理方法中的催化氧化技术,总结了近年来几种主要类型的碳烟燃烧催化剂(贵金属催化剂、碱金属催化剂、单组分过渡金属氧化物催化剂、多组分混合氧化物催化剂和固定结构复合氧化物催化剂)的最新研究进展,并对该研究方向存在的主要问题和应用前景进行了探讨。Soot particulate emitted from diesel engine exhaust has led to serious atmospheric pollution and it must be purified or treated. It is necessary to apply highly active catalysts during the catalytic combustion of diesel soot particulate at lower temperatures. In view of the catalytic after-treatment technique for the treatment method of diesel soot particulate, the latest research progress in major types of catalysts for diesel soot combustion （ noble metal catalysts, alkali metal catalysts, simple metal oxide catalysts, multiple-component mixed oxide catalysts, complex oxide catalysts with fixed structure） were summarized, and some tentative suggestions for the main problems in this research area and potential application prospects were also put forward.
