Cleaning up their act : A novel CO 2 ‐stable and cobalt‐free dual‐phase membrane for oxygen separation from air has been developed that consists of 40 wt % NiFe 2 O 4 and 60 wt % Ce 0.9 Gd 0.1 O 2− δ . This membrane shows a steady oxygen permeation flux over 100 h using CO 2 as sweep gas at 1000 °C.
