TbFeO_3 was prepared by the complex Method with citric acid.Its perovskitestructure was measured by XRD. The rate constant of reduction step for TbFeO_3 has beenmeasured hy the pulse method.The kinetics of CO oxidation over TbFeO_3 has been studiedin an external circulating flow reactor. The experimental data coincide with the Redox mechanism equation. Kinetic parameters of Redox mechanism equation were estimated by themethod of orthogonal design. The reoxidation of reduced catalyst is the control step of COoxidation over TbFeO_3.
