Abstract
A glassy carbon (GC) static disc electrode substrate was employed for both chronoamperometry and to study the morphological growth behaviour of cobalt in sulfate solutions containing 0.10 M and 0.50 M Co2+, at pH 2.5, and 60°C. The effect of potentiostatic pulses on the initial stage of electrodeposition of cobalt is reported. The early stages of metal deposition were found to be controlled by three-dimensional instantaneous nucleation followed by hemispherical growth. The experimental findings for the growth mechanism matched well with the theoretical results and the 3D-growth of cobalt nuclei was confirmed by scanning electron microscopy (SEM).
