Abstract
The kinetics of structural changes in the adlayer formed during underp otential deposition (and dissolution) of copper on Au(111) in sulphuri c acid solution has been investigated by Potential-step experiments. T he measured current transients can be described by a two-dimensional n ucleation and growth mechanism which is accompanied by an adsorption ( desorption) process; the two reactions occur at different sites on the electrode. The potential dependences of adsorption, desorption and gr owth rate obey the Butler-Volmer relation.
