“…Similar results were reported in the case of Rh electrodeposition on Au(100) and were attributed to a decrease of the radial growth rate of the 2D Rh clusters provoked by the presence of various surface inhomogeneities (11). A decrease of the radial growth rate can be expected also in the case of a surface diffusion-controlled growth of 2D clusters (10,12,13). A new model including 2D nucleation and surface diffusion-controlled growth has been developed and applied successfully for the description of current transients for the anodic deposition of a calomel monolayer on mercury (14).…”

Underpotential deposition (UPD) of Cd on Ag single crystal substrates has been studied by in situ scanning tunneling microscopy (STM) and electrochemical measurements. On Ag(111) the UPD process starts with formation of an expanded adlayer. This adlayer transforms by 2D nucleation and growth to a condensed Cd monolayer, which is unstable and at long polarization times undergoes changes involving surface alloy formation phenomena. In contrast to Ag(111), on Ag(100) a formation of a condensed monolayer by 2D nucleation and growth has been observed at relatively high underpotentials. The growth rate of 2D clusters extracted from the in situ STM images indicates a surface diffusion-controlled growth kinetics. At lower underpotentials the UPD of Cd on both substrates involves a significant surface alloy formation, which is reflected in the surface topography changes observed during the anodic stripping.

Electrochemical deposition of aluminum from NaA1C14 melts saturated with NaC1 onto a glassy carbon electrode at 175~ has been studied by voltammetry, chronoamperometry, and constant current deposition. The deposition of aluminum was found to proceed via a nucleation/growth mechanism, and the nucleation process was found to be progressive. The morphology of aluminum deposits was examined with photomicroscopy. It was shown that depending on the current densities (c.d.) applied, three types of aluminum deposits could be obtained, namely, spongy deposits formed at lower c.d.

“…The results were fit to the well-established metal electrocrystallization theory. 10,[112][113][114] In general, the hydrophilic monomer such as carboxylic acid (PPA) undergoes progressive nucleation (rate of nucleation is much faster than the rate of nuclei growth), suggesting good interaction of moderately hydrophilic stainless steel surface with the hydrophilic deposit. Conversely, the EP of hydrophobic ester derivative proceeds through instantaneous nucleation, whereby nuclei growth dominates over nucleation.…”
