Abstract
Gold electrodeposition has been studied on glassy carbon from Au(I) am moniacal 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. Diffusion coefficients were calculate d for Au(I) at different temperatures. It was also found that the incr ease in the temperature provokes the modification of the nucleation me chanism.
