Abstract

The novel Fe/Nb co-doped SrCo_{1 - 2x}(Fe,Nb)_xO _{3 - δ} (x = 0.05, 0.10) perovskite oxides were synthesized by the solid-state method. Structural and chemical stability of the SrCo _{1 - 2x}(Fe,Nb)_xO_{3 - δ} (x = 0.05, 0.10) oxides were studied by differential scanning calorimetry (DSC), thermogravimetric analysis (TG) and X-ray diffraction (XRD). The results demonstrated that the structural and chemical stability of the Fe/Nb co-doped SrCo_{1 - 2x}(Fe,Nb)_xO_{3 - δ} (x = 0.05, 0.10) is improved significantly. The oxygen sorption properties of the SrCo _{1 - 2x}(Fe,Nb)_xO_{3 - δ} (x = 0.05, 0.10) oxides were investigated between 300-900 °C in air, and the high oxygen sorption capacity of 11.5 and 10.3 mL O₂ (STP)/g oxide, respectively, are obtained.
