Abstract
A multi-scaled oxygen storage material wherein cobalt element is complexed with a size of an atom or hundreds of nanometers or smaller in a ceria-zirconia solid solution and a method for preparing the same as provided. Specifically, the multi-scaled oxygen storage material contains a ceria-zirconia solid solution, a cobalt doping contained in the solid solution in the form of an atom and a cobalt-based nanocluster dispersed in the solid solution as cobalt oxide and exhibits a microstructure distinguished from that of the existing ceria-zirconia (CZO)-based oxygen storage material as well as remarkably improved oxygen storage and release ability, and the method for preparing the same is provided.
