“…Regarding electrodeposition studies conducted in reline, several examples have been published in the last two years: for instance, water-soluble magnetic iron oxide nanoparticles were prepared at the anode during the electrolysis of reline using iron electrodes [ 95 ]; ruthenium nanoparticles were electrodeposited on stainless steel from a dichloride solution [ 96 ]; core–shell Pd-hydroxide NPs were obtained through the electrochemical oxidation of formic acid [ 97 ]; Zn/ZnO nanopowders were electrodeposited over Pt electrodes electrolyzing ZnCl 2 solutions [ 98 ]; copper nanoparticles were obtained from CuCl 2 ·H 2 O [ 99 ]. Some of the other “traditional” mixtures prepared in the first phase of DES development together with reline—namely, ethaline (choline chloride-ethylene glycol) and glyceline (choline chloride-glycerol)—have found a considerable number of applications recently.…”

Deep Eutectic Solvents have gained a lot of attention in the last few years because of their vast applicability in a large number of technological processes, the simplicity of their preparation and their high biocompatibility and harmlessness. One of the fields where DES prove to be particularly valuable is the synthesis and modification of inorganic materials—in particular, nanoparticles. In this field, the inherent structural inhomogeneity of DES results in a marked templating effect, which has led to an increasing number of studies focusing on exploiting these new reaction media to prepare nanomaterials. This review aims to provide a summary of the numerous and most recent achievements made in this area, reporting several examples of the newest mixtures obtained by mixing molecules originating from natural feedstocks, as well as linking them to the more consolidated methods that use “classical” DES, such as reline.

“…The driving force of a reaction can be controlled and the thermodynamic and kinetic parameters can be measured [1]. A great deal of interest in modern electrochemistry has been intended for the metal electrocrystallization on various substrates [2][3][4]. The physico-chemical properties of electrodeposits are determined by the nucleation kinetics and the growth of metallic nuclei on the substrate [5].…”

By using cyclic voltammetry (CV) and chronoamperometry (CA) techniques, the thermodynamics and kinetics of palladium electrodeposition on glassy carbon electrode (GCE) in deep eutectic solvent were studied. The Pd electrodeposition process via progressive 3D nucleation mechanism was controlled by the diffusion. Non-linear fitting methods were applied to obtain the kinetic parameters in the light of Harrison – Thirsk (H-T) and Scharifker – Hills (S-H) models for 3D nucleation and growth process. From that, the diffusion coefficient of Pd (II) in reline at ambient temperature was calculated by two different ways, and the obtained results showed that it is of cm2/s by using CV. Moreover, some important parameters such as the number density of active sites on the electrode surface (No) and the nucleation frequency per active site (A) were estimated by fitting experimental CAs data with Scharifker-Mostany model.

“…2,3 In particular, gold nanoparticles, AuNPs, have been successfully used to eradicate tumors during hyperthermic therapy. 4 MeNPs have also been applied to modify electrodes in order to use them for clean energy production in both: proton exchange (PtNPs) 5 and direct alcohol (PdNPs) 6,7 fuel cell devices and to generate energy from photoelectrochemical and electrochemical water splitting (Ti). [8][9][10] Furthermore, MeNPs modified electrodes have proven to be effective catalytic support materials for the development of electrochemical sensors for the quantification of diverse important substances, namely: Dopamine (AuNPs), 11 methanol (PtAuAg nanotubes), 12 DNA (AuNPs and Au-Fe (core-shell).…”

“…Overall, DES are friendlier with the environment and are more affordable. Furthermore, from DES the electrochemical nucleation and growth of MeNPs of Ni, 16 Fe, 17,18 Al, 19,20 Pd, 6,7,21,22 Cr, 23,24 and alloys (Ni-Co) 25 can be achieved. Due to the above mentioned, this work will deal with the mechanism and kinetics of the electrochemical nucleation and growth of AuNPs onto a GCE, from Au(III) ions dissolved in reline (DES formed by the eutectic mix of choline chloride and urea), and its influence on the electrochemical quantification of DA in presence of one its major interferents, uric acid (AU).…”

The mechanism and kinetics of the electrochemical nucleation and growth of gold nanoparticles (AuNPs) onto a glassy carbon electrode (GCE) from Au(III) dissolved in the reline deep eutectic solvent, DES, at 70ºC, were assessed. From the potentiodynamic technique it was found that gold electrodeposition onto the GCE is a diffusion-controlled process. The potentiostatic current density transients, recorded during the electrodeposition of AuNPs were described by a mechanism where multiple nucleation of 3D gold centers with mass-transfer controlled growth, occurs simultaneously with Au(III) adsorption and the DES residual water reduction on Au nuclei.. From scanning electron microscopy images and energy-dispersive X-ray spectra of the GCE, electrodeposited with gold (GCE/AuNPs), it was found that Au deposit was formed by aggregates, (183 ± 37) nm average size, of AuNPs (of ca 50 nm diameter). The GCE/AuNPs was used for the Dopamine, DA, electrochemical quantification in the presence of uric acid, UA, with the following analytical performance: sensitivity of (32.49 ± 0.37) μA mM-1 and (28.6 ± 0.2) μM detection limit
