Electrocatalytic activity of core-shell Au@Pt nanoparticles for the hydrogen oxidation reaction

► Use of core-shell Au@Pt nanoparticles as electrocatalyst for the hydrogen oxidation. ► Almost the same electrocatalytic activity than Pt nanoparticles. ► The material is useful to reduce the amount of Pt in the anode of a fuel cell. ► The role of the active area factor in the evaluation of the kinetic parameters.
