A mixed ionic and electronic conducting dual-phase oxygen permeable membrane with high CO tolerance
Dual-phase membranes have been successfully developed using x wt% Ce 0.9 La 0.1 O 2− δ and 100 − x wt% La 2 CuO 4+ δ ( x CLO-(100 − x )LCO) with no alkaline earth metals contained in the system. The 60CLO-40LCO dual-phase membrane exhibits the highest oxygen permeation rate of 0.25 mL min −1 cm −2 u...
