Original Paper


The contact angle between growing clusters and the electrode surface is taken into consideration in the description of potentiostatic current transients during nucleation and diffusion-controlled growth of three-dimensional phases. It is shown that the non-dimensional plots of the currents normalized with respect to their maxima, and the nucleation rates obtained from analysis of experimental transients are unaffected by the contact angle. The results obtained reveal, however, that consideration of contact angles different from 90° in analysis of experimental current transients lead invariably to lower number densities of active sites for nucleation.
