N2 - A series of (Ba,Ca)(Co,Fe)O3-δ membrane materials were synthesized through Pechini method. The structure, the oxygen flux, and the permeation stability of the materials were examined, and their application in oxidative coupling of methane was also attempted. The materials showed a high oxygen flux and good stability. The oxygen flux through Ba0.95Ca0.05Co 0.8Fe0.2O3-δ was 1.4 mL/sq cm·min) at 950°C, and remained unchanged within 160 hr at 850°C. The C2 selectivity was high, but the CH4 conversion was low.
