High temperature gas separation through dual ion-conducting membranes

[摘要] Here we provide an overview of recent developments in high-temperature electroceramic oxides for the transport of gas-phase species via dual ion conductivity. The electroceramic oxide is used in the form of a dense membrane when it exhibits ionic conductivity for two distinct ions and as a porous host matrix supporting a guest liquid-phase ion conductor when it supplies a path for a single ion, the path for the other being supplied by the liquid phase. We focus on water transport and carbon dioxide transport in single and dual phase membranes, respectively.
