综述了 SCO 法(选择性催化氧化法)中催化剂的研究现状。从过渡金属元素、稀土元素、贵金属、活性炭四类催化剂进行了介绍。锰类复合氧化物催化剂具有较高的催化活性，且成本较低。钙钛矿催化剂的催化活性能与贵金属类催化剂相媲美。这些非贵金属催化剂成本都较低，具有潜在的应用价值。但总的来说目前对于催化剂抗硫抗水的研究还不够深入，一些催化剂可能还未达到实际工业应用中应具有的抗中毒能力。总结分析了 SCO 法应用中存在的问题，展望了其应用前景。

The research status of the catalyst in the SCO method (Selective catalytic oxidation)were summa-rized.It introduces four kinds of catalysts,which including transition metal oxides,oxides of rare earth elements, precious metals,and activated carbon.The composite oxides catalysts of manganese exhibit good performance,which is cost-low.The activity of rare-earth perovskite structure catalysts can be comparable with that of noble metal cata-lysts.All these non-noble metal catalysts is cost-low,it has potential application value for industry.But now the re-search of poison tolerance of the catalysts is less,the tolerant ability for poisoning of the catalysts still could not reach the requirements of practical application.We also analyze the problems existing in the application of SCO and the out-look of the SCO method.
