Effects of Nb and Sn co-doping on the structure and properties of SrCoO3-δ oxygen transport membranes

The structure and oxygen permeability of SrCo0.9-xNb0.1SnxO3–δ (x = 0, 0.03, and 0.05) perovskite membranes were systematically investigated by co-doping the B-site of SrCoO3–δ oxide with Nb and Sn...
