In this work, carbon Vulcan XC-72 (C) and carbon nanotubes (CNTs) supported ternary platinum-ruthenium-iron (PtRuFe) and platinum-ruthenium-nickel (PtRuNi) alloy nanoparticles have been synthesized by a co-reduction method. The catalyst samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), and cyclic voltammetry (CV). The results show that ternary alloy catalysts are always better than binary alloy catalysts. In particular, PtRuNi is the best catalyst for methanol oxidation reaction.
