Effect of A-site lanthanum doping on the CO2 tolerance of SrCo0.8Fe0.2O3a-I' oxygen-transporting membranes

The SrCo0.8Fe0.2O3aI' (SCF) perovskite was systematically doped with increasing lanthanum content up to 60 wt% on the A-site to investigate the effect on CO2 tolerance. Different powders were prepared by a sol-gel method and the materials were characterized by in-situ X-ray diffraction (XRD) an...
