Résumé : The adsorption of silver onto Au(111) and stepped Au(111) in sulphuric acid has been investigated in the underpotential deposition (upd) region using cyclic voltammetry in combination with UHV-based methodologies. We report data showing that the first stage of silver upd is strongly dependent on the superficial state of the substrate and on the formation of a Ag-Au surface alloy. In the absence of the surface alloy, the sharp intense upd peak obtained at 0.53 V (vs. Ag+
