Abstract

The activation of a platinum electrode in an acid sulfate solution is studied on rotating and stationary disk electrodes by means of cyclic voltammetry. Rates of the adatom layer formation and the phase copper deposition significantly increase following use of a slow potential scan and/or agitation of electrolyte as a result of the interaction between adatoms or ions of copper with adsorbed or dissolved oxygen. Oxide compounds of copper are active centers of a two-dimensional growth of an adatom layer and a three-dimensional nucleation in the course of electrocrystallization.
