Abstract

A novel dual phase composite oxygen transport membrane (Al_0.02Ga_0.02Zn_0.96O_1.02–Gd_0.1Ce_0.9O_1.95−δ) was successfully prepared and tested. This membrane shows chemical stability against CO₂ and SO₂, and stable oxygen permeation over 300 hours in CO₂ was demonstrated. ZnO is cheap and non-toxic and is therefore highly advantageous compared to other common materials used for this purpose.
