摘　　要：阐述了汽车尾气净化Pd催化剂的技术特点、现状及展望,分析了Al2O3、稀土氧化物对汽车尾气净化Pd催化剂性能的影响,对比了不同制备方法的优异性,讨论了单Pd催化剂的可行性和实用价值,以及未来的研究方向、技术难点和热点。The features and actualities of palladium automotive catalysts technology were reviewed in this paper. The effects of alumina washcoat and rare earth oxides on catalytic activity of palladium automotive catalysts were analyzed systematically. Distinctness of different methods for preparation of catalysts was discussed. The price fluctuation of precious metals in the market and good catalytic activity of palladium immediately affect the future mainstream of palladium automotive catalysts. The feasibility and value of the application of palladium automotive catalysts were considered. The research direction and technology nodus and hot points of palladium automotive catalysts in the future were put forward.
