摘　　要：近30年来,炭黑还原NO反应引起各国环境研究工作者的关注。本文综述了近年来炭黑还原NO方面的研究进展,着重分析了纯NO-炭黑还原的反应机理,探讨了目前比较常用的实验反应仪器,在不同的反应温度范围可使用不同的反应仪器,且NO-炭黑反应的产物也各不相同,在低温下(<300℃)主要发生吸附反应,高温下发生还原反应。最后简要叙述了不同气氛以及催化剂的存在对反应的影响,不同的反应气氛对NO-炭黑反应的影响各不相同,凡能促进炭黑表面活性位生成的物质均可起到促进反应的作用。Over the last three decades reduction reactions involving soot and NO have attracted the attention of environmental research workers worldwide.The authors have given an overview of the recent research progress on the above-mentioned reduction reactions with an emphasis on the reduction reaction mechanism of pure NO and soot.The experimental instruments nowadays being often used are discussed.Various kinds of reaction instrumentation can be employed for different ranges of reaction-temperature and the various products thus obtained as a result of the NO-soot reaction are also quite different.At low temperatures(less than 300 ℃) an adsorption reaction will mainly take place,while at high temperatures a reduction reaction occurs.Finally,a brief description is given of the impact of the different atmospheres and the presence of catalysts on reaction results.Different reaction atmospheres will have different impacts on NO-soot reactions.All substances,which promote the generation of an activated potential on a soot surface,can invariably be conducive to the progress of reactions.
