钙钛矿型LaMO_3系列对CO_2甲烷化反应的催化性能研究

Activity Research on Perovskite Type LaMO 3 for CO 2 Mathanization Reaction

合成了稀土复合含氧化合物ＬａＭｎＯ３，ＬａＣｏＯ３，ＬａＣｒＯ３。利用ＸＲＤ测定了其晶体结构，进行了ＣＯ２甲烷化的催化活性测试，对其反应机理进行了分析，并认为属于表面上的反应。

Rare earth composite oxides LaMnO 3、 LaCoO 3、 LaCrO 3 were synthesized.The crystalline structure were measured.The catalytic activity for CO 2 mathanization reaction were tested.We explained the machanism of reaction and regarded them as the superfacial catalysis.
