“…The voltammogram of microelectrode filled with PbO powders is initiated from +1.00 V when the potential is scanned in the negative direction and reversed at −1.40 V in the positive direction. From the cyclic voltammetry curve, no significant current is observed until the potential reaches point 'A' (−0.62 V), corresponding to the direct electrochemical reduction of PbO to lead, then the current increases sharply to point 'B' (−1.40 V) where it is reversed [33,34]. This result in a decrease in current which subsequently reaches zero at the crossover potential 'A' and a nucleation loop is apparent.…”

“…Several researching groups have investigated the use of ILs as solvents for the extraction of base metals, precious metals, and rare earth metals with very promising results [6][7][8][9][10]. In addition, the electrodeposition of high-value metals that are more electroactive than hydrogen, like Li, Na, Al, Mg, Ti, lanthanides, and actinides, has also been evaluated in ILs [7,[11][12][13]. ILs are considered to be the most promising possible extracting agents studied over the last years, due to their low toxicity and imperceptible environmental impacts.…”

Today, the primary aluminum production is based on two processes: (a) the Bayer process and (b) the Hall-Heroult process. Both processes deal with several economic and environmental drawbacks. The production of aluminum is an energy intensive process, consuming 53-61 GJ/t of aluminum, while huge amount of red mud and gaseous emissions are inevitably produced through the whole process. The utilization of a new family of solvents called ionic liquids (ILs) in the primary aluminum production is the subject of this paper, which examines the possibility of dissolving metallurgical alumina, hydrated alumina, and bauxites in 1-ethyl-3-methyl-imidazolium hydrogen sulfate ([Emim]HSO 4 ). The results show that hydrated alumina can be dissolved relatively easily at 210 C, forming a melt that contains 9% w/w of dissolved alumina, which is higher than the alumina content in Hall-Heroult melts. Bauxites can also be directly dissolved in this IL with iron presenting higher dissolution than aluminum, while silicon dissolution is negligible.

“…Several studies have recently appeared on electrodeposition of refractory metals, including Ta [30][31][32], Mo [33], Nb [34][35][36], and Ti [37,38], from ionic liquids. Like Si, Ta electrodeposition from ionic liquids is quite challenging, with possible complications that may include incomplete reduction to Ta(0), porous deposits that may trap ionic liquids, and crack formation [30].…”

Electrochemical methods are attractive for thin film deposition due to their simplicity, conformal and high rate deposition, the ability to easily make multilayers of different composition, ease of scale-up to large surface areas, and applicability to wide variety of different shapes and surface geometries. However, many elements from periodic table of commercial importance are too active to be electrodeposited from aqueous solution. Recent advances are briefly reviewed for room temperature methods for electrochemical deposition, including electrodeposition from ionic liquids, electrodeposition from organic solvents, combined electrodeposition and precipitation on liquid metal cathodes, and galvanic deposition. Recent studies of electrodeposition from ionic liquids include deposition of thick (40 µm) Al coatings on high-strength steel screws in a manufacturing environment; deposition of continuous Si, Ta and Nb coatings; and numerous interesting mechanistic studies. Recent studies of electrodeposition from organic solvents include Al coatings from the AlCl3-dimethylsulfone electrolyte, which demonstrate that additives can be employed to suppress impurity incorporation and to improve the deposit quality, and thick (5-7 µm) and continuous Si coatings from SiCl4 in acetonitrile. Galvanic deposition of Ti, Mo and Si coatings onto Al alloys has recently been reported, which is potentially much simpler and less expensive than electrodeposition from ionic liquids and organic solvents, but has complications associated with substrate consumption and coating adhesion.
