| Abstract: | The perovskite structure of DyFeO3 was measured by XRD. The Redox mechanism was proved by the reduction of DyFeO3 with CO and the reoxidation of reduced catalyst with O2 by pulse method. The kinetics of oxidation for CO over DyFeO3 obeyed the Redox mechanism equation. The parameters in equation were estimated by the method of orthogonal design. The relationship of reaction order with respect to CO between the exponential rate equation and the Redox mechanism equaion was dicussed. |
