| 摘 要： | ＧｄＦｅＯ３用柠檬酸络合制备。用ＸＲＤ测定ＧｄＦｅＯ３为钙钛矿结构。用ＣＯ还原脉冲及用Ｏ２再氧化脉冲证实在ＧｄＦｅＯ３上ＣＯ氧化为Ｒｅｄｏｘ机理。用外循环流动无梯度反应顺研究了ＣＯ氧化稳态动力学。用正交设计法估计动力学方程中的参数。还原催化剂再氧化为控制步骤。

| Abstract: | GdFeO_3 was prepared by the compplex method with citric acid .The perovskite struc-ture for GdFeO_3 was determined with XRD. The Redox mechanism for oxidationof CO wasproven by the pulse method of reduction with CO and reoxidation with O_2 over GdFeO_3 cata-lyst.The steady-state kinetic of oxidation for CO was inverstigated with external circulationflow reactor,The parameters of kinetic equation were estimated by the method of orthogo-nala design. The control step is the reoxidation of reduced catalyst. |
