Abstract:
A catalyst that includes cerium oxide having a fluorite lattice structure is provided. The cerium oxide includes cerium atoms in mixed valence states of Ce3+/Ce4+, in which the ratio of Ce3+/(Ce3++Ce4+) in the lattice ranges from 40% to 90% at 20° C. The valence states Ce3+ and Ce4+ are reversible in reduction and oxidation reactions, and the cerium oxide maintains catalytic ability at temperatures at least up to 450° C.
