Abstract

Here, the modulation of the Pt electronic structure by the formation of an amorphous WO_x overlayer on Pt nanoparticles is proposed. The resulting Pt/WO_x@NC electrode shows exceptional CO oxidation potential (0.24 V vs. RHE) in aqueous test, and the corresponding membrane electrode assembly (MEA) steadily generates power in fuel cells fed with H₂ gas containing 1000 ppm CO.
