摘要：

Gold electrodeposition has been studied on glassy carbon from Au(I) 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. Diffusion coefficients were calculated for Au(I) at different temperatures. It was also found that the increase in the temperature provokes the modification of the nucleation mechanism.
