Abstract
The present disclosure relates to a PtAu nanoparticle catalyst heat-treated in the presence of carbon monoxide (CO) and a method for preparing same. Since the PtAunanoparticle catalyst heat-treated under CO atmosphere has high Pt surface area and superior oxygen reduction reaction (ORR) activity, a high-efficiency, high-quality fuel cell can be achieved by applying the catalyst to a fuel cell.
