Abstract
Oxide solid solutions of praseodymium and cerium are useful as the oxygen carrier in a reversible cyclic oxidation-reduction process for separating oxygen from air. The adverse affects on redox rates of contaminants in the air, such as CO.sub.2 and/or H.sub.2 O are substantially eliminated by incorporating a surface dopant such as silver into the praseodymium-cerium oxide.
