The electrochemical hydrogen oxidation reaction activity of a well-defined Ir–Ru bimetallic surface alloy is closely related to Ir/Ru atomic ratios and Ir-dimer (Ir2) and/or trimer (Ir3) ensemble probability at the topmost surface.

Introduction Nanoparticles of Pt as well as Pt-based alloys are widely used as cathode catalyst materials for proton exchange membrane fuel cells (PEMFC). However, electrochemical stability of the materials is rather low under practical operating con
