Abstract

The present invention relates to a nanocatalyst for oxidation having a mesoporous ceria shell, and to a method for complete oxidation of carbon monoxide and hydrocarbon using the same. More specifically, the present invention relates to a nanocatalyst for oxidation, and to a method for complete oxidation of carbon monoxide and hydrocarbon using the same, the nanocatalyst having a core-shell structure in which a ceria shell having mesopores surrounds a core obtained by immobilizing precious metal nano-particles on spherical nano-particles. This nanoparticle catalyst having a mesoporous ceria shell according to the present invention has an advantage in that an excellent conversion rate is exhibited during the complete oxidation of carbon monoxide and hydrocarbon compared to a conventional catalyst having a shell such as mesoporous silica. In addition, there is an advantage in that, unlike a catalyst using a general ceria carrier, high activity is maintained even after firing.
