Abstract

The present invention relates to one kind of nanometer composite La-Ce-Zr oxide. The nanometer composite La-Ce-Zr oxide is one kind of solid solution type composite oxide prepared through adding La into composite Ce-Zr oxide. It includes CeO2 in 20-96 wt%, ZrO2 in 10-86 wt% and La2O3 in 5-56 wt%; and has crystal grain size of 400 nm and BET process measured specific surface area of 200-700 sq m/g. The present invention is used as ideal after burning catalyst for automobile.
本发明涉及一种纳米镧铈锆复合氧化物;在铈锆复合氧化物中加入镧,形成镧铈锆复合氧化物;是一种新型固熔体类型的多元复合化合物,它包括20~96%(重量)的CeO
