CO₂‐Stable and Cobalt‐Free Dual‐Phase Membrane for Oxygen Separation

Abstract

Cleaning up their act: A novel CO2-stable and cobalt-free dual-phase membrane for oxygen separation from air has been developed that consists of 40 wt % NiFe2O4 and 60 wt % Ce0.9Gd0.1O2−δ. This membrane shows a steady oxygen permeation flux over 100 h using CO2 as sweep gas at 1000 °C. Detailed facts of importance to specialist readers are published as ”Supporting Information”.
