On the electrodeposition of nickel–zinc alloys from a eutectic-based ionic liquid

Liquid Nickel Salts: Synthesis, Crystal Structure Determination, and Electrochemical Synthesis of Nickel Nanoparticles

“…[33][34][35][36] Although nickel is mostly electroplated from aqueous electrolyte baths,t he use of non-aqueous electrolytes has been described before,f or examplen ickel electrodeposition from haloaluminate ionic liquids, [37,38] from conventionali onic liquids, [39][40][41] and from deep-eutectic solvents. [42] Non-aqueous electrolytes offer advantagesi nc ertain applications, such as the synthesis of composite nickel coatings with co-deposited luminescent particles [43] and the deposition of nickel-zinc alloysa sp recursors for supported Raney catalysts. [44] Here, we report the synthesis of new nickel(II)-containing ionic liquids with N-alkylimidazole ligands and different counter anions.…”

Catalytically active gauze-supported skeletal nickel prepared from Ni–Zn alloys electrodeposited from an acetamide–dimethyl sulfone eutectic mixture

“…The elemental analysis reveals that the alloys deposited at a potential of −0.3 V vs. Ni/Ni 2+ contain almost pure nickel, while the alloys deposited at potential range between −1.5 and −0.6 V vs. Ni/Ni 2+ contain between 30 and 70 wt.% of nickel. The anodic peak A 1 corresponds to the preferential dissolution of zinc, while peaks A 2 and A 3 correspond to the dissolution of nickel-zinc alloys from zinc rich phases and nickel rich phases, respectively [29,33]. By evaluating the integrated peak areas of anodic and cathodic cycle on the CV, the charge efficiency of the electrodeposition and dissolution of the nickel-zinc alloys is found to be nearly 100%.…”

“…chloroaluminate ionic liquids). Electrodeposition of metals [28], alloys [29], and composites [30] from deep-eutectic solvents was recently explored. Previous work from our labs has demonstrated that the eutectic mixture of acetamide and dimethyl sulfone (DMSO 2 ) with dissolved metal salts is an excellent non-aqueous electrolyte for the electrodeposition of nickel or cobalt with embedded rare-earth phosphor particles [31].…”

Main chemical species and molecular structure of deep eutectic solvent studied by experiments with DFT calculation: a case of choline chloride and magnesium chloride hexahydrate

“…Abbott et al [9] reported electrodeposition of copper composites from deep eutectic solvents based on choline chloride. Yang et al [10] studied the electrodeposition of nickel-zinc alloys from a eutectic-based ionic liquid. Recently, Wang et al [11] reported electrochemical deposition of magnesium from analogous ionic liquid based on dimethylformamide.…”
