Abstract
The present invention features a method for preparing core-shell nanoparticles supported on carbon. In particular, the present invention features a method for preparing core-shell nanoparticles supported on carbon, including: dispersing core nanoparticle powder supported on carbon in ethanol; adding a metal precursor which forms a shell and hydroquinone thereto; and mixing and reducing the same. Preferably, the disclosed method for preparing core-shell nanoparticles supported on carbon enables coating of transition metal nanoparticles including platinum on the surface of core metal nanoparticles at a monolayer level. Prepared core-shell nanoparticles of the present invention may be useful as catalysts or electrode materials of fuel cells.
