“…The kinetic parameters obtained show that the presence of [BMIM]HSO 4 has an inhibiting efect on the kinetics of the copper discharge process with slight changes in the copper electrodeposition reaction pathway, indicated by the changes in Tafel slopes and the corresponding charge transfer coeicient [21]. A possible mechanism of the action of this additive may .…”

“…The complex-plane impedance spectra obtained from the additive-free solution exhibit two capacitive features at high frequencies followed by an inductive loop at low-frequency values (Figure 4a Pyridinium-based ionic liquids were also found to be readily adsorbed on the metallic surface similar to that of imidazolium-based ILs [21], which provide a larger potential group to be researched as novel metal electrodeposition additives. We have previously studied the efects of two alkylpyridiniumILs (py-iLs), including N-butylpyridinium hydrogen sulphate (BpyHSO 4 ) and N-hexylpyridinium hydrogen sulphate (HpyHSO 4 ), on copper electrodeposition from acidic sulphate electrolyte [22].…”

“…Some of the most important prosperities of ILs are their thermal stability and avirulence, which make them potential additives for metal electrodeposition and green inhibitors for metal anti-corrosion. In our previous studies, alkylimidazolium, alkylpyridinium and quaternary ammonium-based ionic liquids were observed to be an excellent levelling agent in zinc [18][19][20][21][22] and copper [23][24][25] electrodeposition and showed favourable corrosion resistant on metals such as aluminium [26], copper [27] and mild steel [2].…”

Ionic liquids (ILs) are molten salts with a melting point of 100°C or below and solely consist of cations and anions. As a kind of novel green solvent, ILs have been obtained broad and deep investigations, and enormous progresses in various ields have been made during the recent 20 years. Despite the fact that the application studies of ILs have been proposed in various ields, no processes have yet been developed to an industrial scale. However, the main interests are still focused on their industrial applications. In this chapter, two perspective applications of ILs in electrochemical ields including additives for metal electrodeposition and inhibitors for metal anti-corrosion were introduced.

“…It has been shown that ILs could be advantageous over conventional leveling agents for zinc electrodeposition [16,17]. We have also previously reported on the use of imidazolium- [18] and alkylpyridinium-based [19,20] ILs as additives in copper electrodeposition from acidic sulfate electrolyte. Both these two kinds of ILs are found to function through their adsorption on the cathodic surface, which inhibit the kinetics of the Cu 2?…”

The effect of quaternary ammonium-based ionic liquids (ILs) including tetraethylammonium hydrogen sulfate (NEt 4 HSO 4 ) and tetrabutylammonium hydrogen sulfate (NBu 4 HSO 4 ) on copper electrodeposition from acidic sulfate electrolyte was investigated by cyclic voltammetry and chronoamperometric measurements. These ILs were found to have a blocking effect on the copper electroreduction and induced the formation of more leveled and fine-grained cathodic deposits. Analysis of the dimensionless current-time transients indicated that the electrodeposition of copper was involved with instantaneous threedimensional nucleation with diffusion-controlled growth. The addition of ILs induced the instantaneous nucleation to more progressive one. Data obtained from X-ray diffraction spectra revealed that the presence of these ILs strongly affected the crystallographic orientation of the electrodeposited copper with a (220) preferential orientation.
