Abstract

The nucleation and initial crystal growth kinetics by electrodeposition from acidic zinc solutions was studied in the absence and presence of antimony and glue on a glassy carbon electrode. Zinc exhibits instantaneous nucleation under the experimental conditions employed in the potential region from −1600 to −2000 mV (mercurous sulphate reference). At low overpotentials antimony and glue increase the number of nuclei.
