Abstract

Oxygen Transport Membranes with mixed oxygen ionic-electronic conductivity are investigated for in-situ oxygen separation in various processes such as oxy-combustion or catalytic membrane reactors enabling process intensification. Dual-phase composite membranes are of high interest due to the opportunity selecting thermo-chemical stable phases conducting oxygen ions and electrons separately. Recently, we reported a novel composite utilizing a donor doped gadolinium ferrite Gd_0.85Ce_0.15Fe_0.75Co_0.25O₃ as electronic conductor. Here, the composition of this perovskite system is systematically varied and its structural as well as functional properties are investigated. Moreover, the option of a cobalt-free composition is investigated.
