| 摘 要： | 制法不同的ＭｇＯ对甲烷氧化偶联的催化性能相差悬殊，比表面积、ＸＲＤ、ＸＰＳ测试结果表明，在较低的反应温度范围内，比表面积大，则晶格畸变率大、晶粒度小，表面未饱和的配位氧量高的ＭｇＯ有较好的催化性能。

| Abstract: | A series of MgO catalysts prepared by different methods for the catalytic oxidation coupling of methane were investigated.The specific surface area,XRD and XPS measurement results reveal that the catalysts with larger specific surface area,larger lattice distortion,Iess crystal dimension and higher amount of surface unsaturated coordinated oxygen can give higher catalytic activity for the reaction mentioned above at lower temperatures. |
