dc.description.abstractA promising electrocatalyst based on the reduction of Pt2+ ions on the surface of hexagonally close-packed (hcp) Ru core nanoparticles has been prepared by a redox–transmetalation process. This simple synthetic process generates a Pt-on-Ru catalyst with a lower Pt content than commercially available Pt[BOND]Ru electrocatalysts and with a long-range ordered hcp structure, which can significantly reduce the Pt loading. X-Ray absorption spectroscopy of the Pt-on-Ru catalyst reveals pronounced electronic modifications when compared to the commercial Pt[BOND]Ru black catalyst. The Pt-on-Ru catalyst exhibits a higher mass-specific current than the Pt[BOND]Ru black catalyst in solution in 0.5 m H2SO4 with 10 vol. % CH3OH under the conditions of rotating disk experiments. Further optimization of this synthetic procedure may yield even more active electrocatalysts with a significant reduction in noble metal loadings.en_US
