A novel zirconium-based membrane material of BaCo0.4Fe0.4Zr0.2O3-δ with cubic perovskite structure was synthesized for the first time through a method of citric and EDTA acid combined complexes. The structural stability was characterized by XRD, O2-TPD and H2-TPR techniques respectively. The high oxygen permeation flux of 0.873 mL/cm2·min at 950(C was obtained under He/Air gradient. Meanwhile, the single activation energy for oxygen permeation and the long-term steady operation of 200 h at 800℃ were achieved.
