Lead and tungsten double stabilizing cobalt‐based perovskite oxygen permeation membranes for clean energy delivery

In this work, a double site stabilizing cobalt-based perovskite strategy is proposed to enable the feasibility of the oxygen separation membrane. In order to achieve the excellent material stability, the inherently robust lead and tungsten were selected to stabilize cobalt-containing perovskite, respectively. PbxSr1−xCo1−yWyO3−δ (PSCW, 0 ≤ x, y ≤ 1) oxide was prepared by wet chemical process. The oxygen permeation test indicated that Pb and W...
