G. Trejo et al., TEMPERATURE EFFECT ON THE ELECTROCRYSTALLIZATION PROCESSES OF GOLD INAMMONIACAL MEDIUM, Journal of the Electrochemical Society, 142(10), 1995, pp. 3404-3408
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.
