  • Cerium oxide having high catalytic performance
    Patent number: 9561491
    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.

  • METHOD FOR CONVERSION OF CARBOHYDRATE POLYMERS TO CHEMICAL PRODUCTS USING CERIUM OXIDE CATALYST
    Publication number: 20130052708
    Abstract: Methods are described for conversion of carbohydrate polymers, including cellulose, that yield monosaccharide products, including glucose. Catalyst compositions that include functionalized metal/metal oxide clusters on cerium oxide nanostructures are described which provides product yields, e.g., greater that 50% in a single step process.
