This disclosure generally relates to an oxide composition basically composed of cerium and zirconium that has exceptional and stable porosity, surface area and lattice oxygen mobility. The oxide composition can contain one or more other rare earth oxides other than cerium oxide. For example, some compositions can contain one or more of lanthanum oxide, yttrium oxide and neodymium oxide. The oxide composition can be useful as a catalyst, catalyst support, sensor applications and combinations thereof. 本公开内容总体涉及基本上由铈和锆组成的氧化物组合物，其具有特殊且稳定的孔隙度、表面积和晶格氧活动性。所述氧化物组合物可包含除氧化铈之外的一种或多种其它稀土氧化物。例如，一些组合物可包含氧化镧、氧化钇和氧化钕的一种或多种。所述氧化物组合物可作为催化剂、催化剂载体、传感器应用及其组合是有用的。
