Co₂MnO₄/Ce_0.8Tb_0.2O_2-δ Dual-Phase Membrane Material with High CO₂ Stability and Enhanced Oxygen Transport for Oxycombustion Processes.

ABSTRACT: 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 CO₂ atmospheres, which limits their applicability in oxycombustion processes. On the other hand, some dual-phase membranes are stable in CO₂ and SO₂ without permanent degradation. However, oxygen permeation is still insufficient; therefore, intensive research focuses on boosting oxygen permeation. Here, we present a novel dual-phase membrane composed of an ion-conducting fluorite phase (Ce_0.8Tb_0.2O_2-δ, CTO) and an electronic-conducting spinel phase (Co₂MnO₄, CMO). CMO spinel exhibits hig
