摘要
高效汽车排气净化催化剂是实现车外净化的关键因素之一。本文综述了目前国内外关于贵金属、非贵金属和稀土三类汽车排气净化催化剂 ,以及陶瓷蜂窝体和合金蜂窝体二类催化剂载体的研究进展 ,提出了开发汽车排气净化催化剂尚需解决的问题。
High performance catalyst is one of the key factors for purifying the automotive exhaust gases.This paper reviewed the present research and the progress on three kinds of catalyst for purifying automotive exhaust gases,including noble metal catalyst,non noble metal catalyst,and rare earth catalyst.Furthermore,the research and the development trend of the monolithic supports of catalysts were also reviewed,including ceramic honeycomb and alloying honeycomb.In addition,a few problems to be solved were pointed out in the development of the practical three way catalysts.
