The present invention relates to a co-doped cerium oxide represented by the following Chemical Formula 1 and a method for manufacturing the same, and the co-doped cerium oxide of the present invention has high activity and is used as a catalyst for carbon monoxide oxidation reaction. It can be used. [Formula 1] M 1 x M 2 y Ce 1- (x + y) O 2-δ In Chemical Formula 1, M 1 and M 2 are different from each other, each independently a transition metal, x is 0 <x≤0.2, y is 0 <y≤0.2, and δ is 0≤δ≤0.4. |
