Novel dual-phase membranes for CO2 capture via an oxyfuel route

Ceria-based dual-phase membranes showing high oxygen permeation fluxes and stability under a CO2 environment are promising materials for CO2 capture via an oxyfuel route. The high oxygen permeation fluxes compared with other dual-phase membranes are derived from the mixed conducting properties of the perovskite oxides used in the dual-phase membranes.
