“…While the oxidation peak appeared at a potential of -0.53 V, the redox process is considered to be quasi-reversible with two electrons transfer. It seems that the peaks are commonly associated with reduction process of the Cd (II) to Cd(0), as confirmed by other researches [14,15].…”

The cathodic electrodeposition of CdS from aqueous solutions of Cd 2+ and S 2 O 3 2− at 40 °C, has been achieved using a combination of cyclic voltammetric and potentiostatic techniques. The voltammetric responses of the investigated thiosulfate, Cd 2+ both individually as well as with each other are achieved and hence the optimum conditions for the electrodeposition of CdS were determined. Interesting data was obtained and discussed in this work. The mechanism of the electrode reactions for the investigated substance have been evaluated and proposed. X-ray diffraction investigations demonstrate that the electrodeposited CdS is hexagonal polycrystalline in nature. Furthermore, the electrodeposited CdS is of n-type semiconductor was investigated by Mott-Schottky test and from it, donor concentration (N D) is also determined.

“…42 Furthermore, Sankara has reported that the concentration and alkyl chain length of quaternary ammonium ions inhibit electrodeposition reactions. 43 Based on these findings, TMAC can effectively inhibit the electrodeposition reaction of Al in DMSO 2 solvents. Therefore, when performing plating at the same current density as previous studies, 24 it occurs in the potential region in which the side reaction occurs actively.…”

Cyclic voltammetry of a DMSO2–AlCl3 electrolyte was performed using an ultramicro disk electrode to evaluate the effects of ammonium salts on the Al electrodeposition reaction. A side reaction in the electrolyte at potentials more negative than −0.8 V (versus Al-wire) was found to suppress the Al electrodeposition reaction. The addition of even a small amount of NH4Cl promoted an Al electrodeposition reaction, which proceeded at more positive potentials than the side reaction. With the excessive addition of tetramethylammonium chloride (TMAC) electrolyte, the Al electrodeposition reaction was also suppressed, proceeding in the negative potential region where a side reaction occurs. In the electrolyte containing 0.02-mol NH4Cl and 1.0-mol TMAC, a decrease in the deposition overpotential on the reducing side and an increase in the dissolution current on the oxidizing side were observed simultaneously.

“…The effects of electrode materials, bath composition, and additives on cadmium reduction mechanism have been analyzed extensively. [14][15][16][17][18] However, post-baking is sometimes required to prevent the hydrogen embrittlement caused by the negative reduction potential of cadmium species in aqueous solutions. Thus, aprotic ILs are expected to be one of the promising alternatives to the conventional aqueous media because hydrogen evolution does not occur in aprotic ILs.…”

Electrodeposition of Cadmium from Lewis Basic Hydrophobic Room-temperature Ionic Liquid

Electrodeposition of cadmium (Cd) was investigated in a hydrophobic room-temperature ionic liquid, 1-butyl-1methylpyrrolidinium bis(trifluoromethylsulfonyl)amide (BMPTFSA) using CdCl 2 as the source of Cd species in the presence of excess chloride ion. Raman spectroscopy and potentiometric measurement suggested formation of a cadmium tetrachlocomplex, [CdCl 4 ] 2− , in BMPCl/BMPTFSA. Cyclic voltammetry showed the possibility of electrochemical reduction from [CdCl 4 ] 2− to Cd(0) with interesting unusual electrochemical behavior, probably derived from the potential-dependent electric double layer structure typical to the ionic liquid. Electrodeposition of Cd was performed by potentiostatic electrolysis and the deposits were characterized by X-ray diffraction, energy dispersive X-ray analysis and scanning electron microscopy.
