Here, the modulation of the Pt electronic structure by the formation of an amorphous WO overlayer on Pt nanoparticles is proposed. The resulting Pt/WO@NC electrode shows exceptional CO oxidation potential (0.24 V . RHE) in aqueous test, and the corresponding membrane electrode assembly (MEA) steadily generates power in fuel cells fed with H gas containing 1000 ppm CO.
