SrCo 0.8 Fe 0.2 O 3-δ (SCFO) and Ba 0.5 Sr 0.5 Co 0.8 Fe 0.2 O 3-δ (BSCFO) oxides were successfully prepared, using a combined citrate-EDTA complexing method. The results of O 2 -TPD and XRD showed that the introduction of barium into SCFO could effectively suppress the oxidation of Co 3+ and Fe 3+
