Abstract

A series of (Ba,Ca) (Co,Fe)O_3-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 results demonstrated that the materials have a high oxygen flux and a good stability. The oxygen flux through Ba_0.95Ca_0.05Co_0.8Fe_0.2O _3-δ was 1-4 ml/ (cm²·min) at 950 °C, and remained unchanged within 160 h at 850 °C . The C₂ selectivity was high, but the CH₄ conversion was low.
