Carbon-supported Ir, Rh, IrSe, and RhSe were synthesized and subjected to electrochemical and physical (XRD, TEM) characterizations. ORR activity, peroxide generation, and methanol tolerance on carbon-supported Ir, Rh, IrSe, and RhSe were compared to a similarly prepared Pt and RuSe catalysts at comparable loading. Electrochemical characteristics of selenides studied using cyclic voltammetry and Cu stripping demonstrated complete suppression of the formation of oxygenated species and H upd on the catalyst surface by Se. In presence of methanol, all selenides exhibited high methanol tolerance, and their oxygen reduction activities were in the order of Ir<Pt<Rh<IrSe
