摘要
合成了两个稀土复合氧化物ＬａＭｎＯ３和Ｌａ（０．９２７）φ（０．０７３）ＭｎＯ３，并对其进行了结构、电阻率、ＸＰＳ表面分析、水汽转化及二氧化碳甲烷化反应的催化性能测定。初步解释了结构与性能的关系。
Single phase perovskite-type rare earth composite oxides LaMnO3 and La(0.927)Φ(0.073)MnO3, Φ refers to the number of cavities, were prepared by citric acid complex method.Their crystal structure, specific resistance, surface oxygen and catalytic activities for CO2 methanation and CO water-shift reaction were measured.A primary comment on their structure and properties was presented.
