“…These sharply falling currents in the initial parts of transients have often been observed in various electrodeposition systems and are related to the charging of the electrode/electrolyte interface, various processes such as adsorption [62,63], a multistep charge-transfer reaction [64], and the redox process, which influences the state of the substrate surface [65].…”

Preliminary results regarding the electrochemical behavior of Se(IV) in sodium citrate solution on a polycrystalline SnO 2 electrode are presented. A schematic diagram of the energy levels for an n-type SnO 2 electrode in contact with the working electrolyte was constructed. The results of cyclic voltammetry (CV) show that SeO 3 2− reduction occurs through a surface state in a complex multistep pathway. After a minute amount of Se is deposited, the electrode is expected to behave locally like a Schottky diode in contact with the solution. CV analysis and current transient results indicate that selenium growth on the polycrystalline SnO 2 surface proceeds without nucleation. A thin Se film obtained at a potential of −0.8 V vs. Ag|AgCl, KCl (sat) was analyzed by lateral force and atomic force microscopy.

“…(6)) may lead to the accumulation of Cu + at the electrode surface if the nucleation and growth of copper clusters is not sufficiently fast [25,26]. Accordingly with Milchev et al, an electron transfer reaction takes place prior to and simultaneously with the process of the nucleus formation.…”

“…(8) has been related with the electron transfer reaction, i.e. I et = a R exp(−b R t), discarding an ion transfer reaction [25,26]. The second term describes the current of progressive nucleation and growth of the copper crystals on the substrate, under combined "charge transfer" and "diffusion limitations" [27].…”

“…The study of initial electrocrystalization of metals is an important area of study [7][8][9][10]. A number of studies have been reported for the investigation of the initial nucleation of cobalt [32], copper [14,22,25,27,29,33], palladium [7, 13, 16-19, 21, 23, 34, 36], platinum [20,28] and silver [31] on various substrates. Initial electro-nucleation studies are important as it provides a mechanistic study with simple approach that can be used to approximate the actual initial nucleation without the help of expensive instruments such as atomic force microscopy and other nano-imaging tools.…”

Electrochemical metal nucleation is the method for the formation of metal nanoparticles on the electrode surface. Studying the early stage of electronucleation is simpler than other methods as the driving force for nucleation is achieved by changing deposition potentials and concentration of metal ions. In this work, the potential step electrochemical deposition of palladium was studied from its chloride solution at room temperature on glassy carbon electrode surface. The nucleation mechanism was studied by analysis of the resulting current transients. Accordingly, the initial electro-nucleation mechanism of palladium nanoparticles was found to be varying depending on deposition conditions such as deposition potential and palladium concentration. It can be changed from 3D instantaneous (for all deposition potentials studied and in higher electrolytic concentration) to 3D progressive nucleation mechanism (for lower deposition potential and lower electrolytic concentration). In addition, the nucleation rate for each deposition potential as well as the concentration has been determined. The nucleation rate in this research is used to calculate the nuclei density and found to decrease from more negative deposition potential to more positive deposition potential in agreement with the observed shift in electronucleation mechanism.
