Abstract

The mass-specific activities of the Pt–Co alloy catalysts manifest a typical double-volcano plot as a function of alloy compositions. The Pt₇₆Co₂₄ exhibits the best ORR performance, which is remarkably higher than that of the commercial Pt/C (E-TEK). The origin of the enhancement in the ORR activity may be substantially related to the unique chemical surface structures of catalysts.
