Abstract

Esta descripción se relaciona generalmente a una composición de óxido compuesta básicamente de cerio y zirconio que tiene porosidad excepcional y estable, área de superficie y movilidad de oxígeno de la red. La composición de óxido puede contener uno o más de otros óxidos de tierra rara diferentes del óxido de cerio. Por ejemplo, algunas composiciones pueden contener uno o más de óxido de lantano, óxido de itrio y óxido de neodimio. La composición de óxido puede ser útil como un catalizador, soporte de catalizador, aplicaciones de sensor y combinaciones de los mismos.
