我国汽车尾气净化催化剂的研究现状

Present Status of Research on Automobile Exhaust Purification Catalysts in Our Country

简述了我国汽车尾气净化催化剂现状,并从催化剂载体、催化剂涂层材料、催化剂助剂和催化剂活性组分四个方面作了分析。同时介绍了目前我国催化剂的主要研究和生产情况。随着各国汽车工业的迅猛发展,对催化剂的用量愈来愈多,用廉价的稀土取代贵金属催化剂将是汽车尾气催化剂新的发展方向,具有广阔的应用前景。

The present situation of automobile exhaust purifying catalysts is described in this article, and catalyst carders, catalyst coating materials, catalyst auxiliaries and catalyst active components are introduced respectively. While the current situation of main research and production of our country catalysts is introduced. With rapid development of every state nation automobile industry, the using amount of catalysts is more and more much, by cheap rare earth instead of noble metal catalysts will be the new development direction of car exhaust catalysts, has the broad application foreground.
