<p>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 CO2 and/or H2O are substantially eliminated by incorporating a surface dopant such as silver into the praseodymium-cerium oxide.</p> |
