钙钛矿La_(1-x)Ce_xMnO_3在三元催化剂中的应用

摘要开发研制出一种以钙钛矿La0.6Ce0.4MnO3和贵金属Pt、Pd为主要活性成分的汽车尾气净化三元催化剂,催化剂配方大大降低了贵金属用量。小试评价试验表明,新配方催化剂活性比目前市场上的催化剂催化活性更强。

Abstract： A new auto exhaust three-way catalyst with La_(0.6)Ce_(0.4)MnO_3 perovskite and Pt-Pd as active ingredient was developed in this paper.The quantity of noble metal in the new catalyst was decreased greatly,and so the cost was lowered compared to the similar products in the market.The evaluation tests indicate that the new catalyst has higher activity than the catalyst sold in the market.
