摘要
合成了负载在莫来石上 x值不同的 La2 -x Srx Cu O4(0≤ x≤ 1)系列复合氧化物 ,用 XRD、SEM等方法研究了这类复合氧化物的结构和氧化还原性能 ,考察了对 N2 O分解的催化活性 ,并对反应的宏观动力学进行了讨论 ,认为对于 N2 O的分解是一级反应。
A series of Sr doped perovskite oxides La-{2-%x%}Sr-%x%CuO-4(0≤%x%≤1) supported on mullite were prepared, the structure and redox property were studied by XRD and SEM measurements. The catalytic activity for N-2O decomposition over these oxides was tested. Kinetics study on catalytic decomposition of N-2O showed that it can be described as first order reaction with respect to N-2O.
