摘要: 钙钦矿型稀土钻酸盐及锰酸盐作为汽车废气净化催化剂已作过许多研究,但多数为La的钻酸盐或锰酸盐的衍生物,系统研究稀土元素对催化活性影响的工作还较少,本文探讨了不同稀土离子对REMnO3催化性能的影响,为稀土的开发应用做些基础研究。

Abstract: Perovskitc-type oxides REMnO3(RE=La,Pr,Nd,Sm,Eu,Gd,Dy)were prepared.The effect of REion on catalytic activity of REMnO3 was investigated.The relation among catalytic activity,effective magnetic moment and reducibility of catalysts was discussed.
