Abstract:
A model for the underpotential deposition of metals that occurs in stages is introduced. In this model the deposition takes place as a sequence of first order phase transitions of the adsorbate. In this application we study the underpotential deposition of Cu on a AuIII surface in the presence of sulfate ions. The voltammogram of the deposition shows two sharp spikes which are reproduced by our model.
