1 第 41 卷第 1 期 2013 年 2 月 Vol.41 No.1 METAL MATERIALS AND METALLURGY ENGINEERING Feb (1. 湖南有色金属职业技术学院湖南株洲 ; 2. 湖南稀土金属材料研究院湖南长沙 ) : : ; ; ; ; : X734.2 : A : (2013) Present Status of Research on Automobile Exhaust Purification Catalysts in Our Country YANG Qing-shan 1 LAN Shi-kun 2 (1. Hunan Nonferrous Metals Vocational and Technical College Zhuzhou China; 2. Hunan Rare-earth Metal Research Institute Changsha China) ABSTRACT: The present situation of automobile exhaust purifying catalysts is described in this article and catalyst carriers 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.
