Abstract
Gold electrodeposition was studied on glassy carbon and platinum electrodes from Au(1) ammoniacal solution. The current transients obtained from potential step perturbations, show a typical metallic nucleation growth controlled by diffusion. This process is influenced by adsorption of the different chemical species on the surface. Change in the type of nucleation and morphology of the deposit was observed when the nature of the substrate was changed. It was also found that increase in temperature produces modification of the nucleation mechanism.
