“…3,5,15 As the potential (E) becomes more negative from the open circuit potential (E ocp ), two pre-waves (C 1 , C 2 ) appear prior to the cathodic current due to the bulk breakdown of the electrolyte. It is interesting to note that in earlier work, 4 we observed the similar pre-waves in reline on steel. The cathodic processes observed in the onward scan are accompanied by the two anodic waves A 1 and A 2 .…”

“…2 Due to its importance, there have been many studies on the electrochemical behavior of reline. [3][4][5] The cyclic voltammograms in these studies show that prior to the cathodic decomposition of blank reline, one or two pre-waves are observed when the electrode is polarized cathodically.…”

“…3,12 Water has been shown to induce an enhancement of cathodic pre-waves in reline. 3,4 It is therefore, important to understand the processes responsible for the appearance of pre-waves in voltammograms of reline, and in other deep eutectic solvents.…”

This work investigates the electrochemical role of water in the research of deep eutectic solvent (DES) based on urea and choline chloride. The motivation comes from the growing use of this DES, and on reports where a characteristic voltammetric cathodic pre-wave is observed. However, there has been no direct study to verify if such interpretation of the pre-wave is appropriate. In this regard, cyclic voltammetry has been used in this paper to interrogate the reactions inducing the appearance of the pre-wave. These experiments have been carried out using reline (the eutectic mixture of urea and choline chloride) melts containing different amounts of water, compounds which can be incorporated as impurities from air, or as decomposition products of reline. The analyses showed that a pre-wave in voltammograms in reline originates from water electroreduction accompanied with a subsequent choline hydroxide formation. In this sense, reline behaves like a typical mixture of organic solvent + alkali cation salt + water. The voltammetric signal depends on water content in reline. Importantly, this offers a possibility for in-situ electrochemical determination of water content in reline, provided that a calibration curve is constructed.

The influence of glycerol as an additive in Zinc-Manganese alloy coatings formed by electrodeposition

The aim of this investigation is to evaluate the influence of glycerol (a nontoxic additive) on Zn-Mn coatings formed by electrochemical deposition. The influence of glycerol (GLY) on the electrodeposition of Zn-Mn alloys on Pt from acid baths was studied by cyclic voltammetry. The coatings were analyzed by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The Zn-Mn alloys prepared in the absence or presence of this additive showed similar voltammograms except when using GLY and boric acid (BA) concentrations at 0.63 and 0.24 M, respectively. The current efficiency of the Zn-Mn electrodeposition process ranged from 5 to 41%, due to the lowest and highest concentrations of GLY and BA, respectively. SEM images of deposits obtained at -1.53 V from baths containing 0.08-0.48 M GLY were dendritic, while those formed in the presence of 0.63 M GLY showed that GLY acted as a brightener at this concentration. The XRD analysis showed that the electrodeposits contained Zn, Mn, oxides as well as alloys of various compositions. GLY acted as a grain refiner and inhibited the codeposition of Zn with Mn and the formation of oxides.

“…2 Our group focuses research on Zn-Mn alloy electroplating as a corrosion resistant coating on steel, from aqueous solutions, 3 but we also reported the electrodeposition process of Zn-Mn alloy from deep eutectic mixture of choline chloride and urea, with trade name reline. 4 The motivation for using DES in Zn-Mn electroplating is the fact that water baths suffer from instability, low current efficiency or poor deposit morphology due to the hydrogen evolution reaction. 5 A literature search evidenced that only a few research groups have tackled the possibility of Zn-Mn electrodeposition from choline-based deep eutectic solvents: reline with boric acid as an additive was used for electrodepositing Zn-Mn on copper, 6,7 while acetylcholine chloride-urea eutectic mixture was employed for Zn-Mn electroplating from the leached liquors of spent alkaline batteries.…”

Cyclic voltammetry was used for the characterization of zinc electrodeposition on steel from ethaline deep eutectic solution (1:2 choline chloride:ethylene glycol). The influence of 4-hydroxy-benzaldehyde (HBA) as an additive was analyzed. It was shown that hydrogen evolution is inhibited in the presence of HBA and further significantly retarded upon addition of Zn 2+ to the solution containing HBA. The cathodic peak for Zn 2+ reduction in this type of ionic liquid (ethaline+HBA+Zn 2+) resembles the zinc reduction in aqueous solution. The corrosion resistance of Zn coatings deposited at different current densities was evaluated by electrochemical methods, i.e., polarization measurements and electrochemical impedance spectroscopy in 3 % NaCl solution. The possibility of Zn-Mn alloy deposition from ethaline deep eutectic solvent was investigated for the first time. In addition, the corrosion stability of these alloy coatings was analyzed and compared to the stability of bare Zn coatings. It was shown that the optimum deposition current density for both Zn and Zn-Mn coatings with increased corrosion stability from ethaline + HBA electrolyte is 5 mA cm ˗2 .
