Novel oxygen transport membranes with tunable segmented structures

Abstract

A novel oxygen permeation membrane with a tunable segmented configuration obtained by employing the tape casting technique has been developed. According to this new structure, the membrane consists of a robust fluorite oxide matrix and electron conducting perovskite oxide segments. Mixed electron–ion conduction in the membrane can be optimized by controlling the number of the electron conducting segments. This new concept of the membrane with high oxygen permeability is proposed for the industrial oxygen production.
