The present invention relates to a multi-scale oxygen storage material in which a cobalt element is complexed with ceria-zirconia solid solution at an atomic size or a size of several hundreds of nanometers or less, and a method for producing the same. (CZO) -based oxygen storage material including a ceria-zirconia solid solution, a cobalt doping in an atomic form in the solid solution and a cobalt-based nano-cluster dispersed in a cobalt oxide form in the solid solution, Scale structure and a significantly improved oxygen storage / release capability, and a method of manufacturing the same. |
