A Model for Sequential First Order Phage Transitions Occurring in the Underpotential Deposition of Metals,

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 Au(III) surface in the presence of sulfate ions. The voltammogram of the deposition shows two sharp spikes which are reproduced by our model.
