摘要：

The influence of chloride ions and polyethylene glycol (PEG) on the nucleation of copper on glassy carbon from acid sulphate solutions was studied by measuring potentiostatic current transients (the chronoamperometry method). It was found that instantaneous nucleation occurred at the surface for solutions without additives. The initial stage of copper nucleation did not change on addition of chloride ions, but gradually changed from progressive nucleation to instantaneous nucleation at increasing potentials in the presence of PEG. Chloride ions and PEG increase the nucleation rate and the nuclear number density of nuclei at the surface.
