Oxygen-permeable membranes of Ba1.0Co0.7Fe0.2Nb0.1O3−δ (BCFN) coated with Ru2.0wt%Rh0.2wt%/Co0.3Mg0.7O catalyst have high oxygen permeability and can be used for the production of synthesis gas from methane by partial oxidation. Tests over 160 h show that the oxygen permeation flux is greater than 18 mL(STP)/(cm2 min), substantially exceeding the oxygen permeability of existing perovskite crystal systems.
