CoMnO/CeTbO Dual-Phase Membrane Material with High CO Stability and Enhanced Oxygen Transport for Oxycombustion Processes.

Oxygen transport membranes (OTMs) are a promising oxygen production technology with high energy efficiency due to the potential for thermal integration. However, conventional perovskite materials of OTMs are unstable in CO atmospheres, which limits their applicability in oxycombustion processes. On the other hand, some dual-phase membranes are stable in CO and SO without permanent degradation.
