The rate-determining step in the electro-deposition of copper on copper from aqueous cupric sulphate solutions

Abstract

Different experimental procedures have been employed to establish the slow step in the cathodic growth of copper on freshly crystallized copper substrates. The investigation of intermediates in this electrode reaction is shown to be possible using a rotating single disk electrode. The conclusions drawn from those results are confirmed by the analysis of potentiostatic transients and correspond to the mechanism previously advanced by other workers using alternative experimental techniques.
