Molten salt electrodeposition is the process of producing impressively dense deposits of refractory metals using the electrolysis of molten salts. However, predicting which electrochemical parameters and setup will best control different kinds of deposition (density, homogeneity, etc.) is an ongoing challenge, due to our limited understanding of the properties and mechanisms that drive molten salt electrodeposition. Because these advancements have been made rapidly and in different arenas, it is worth taking the time to stop and assess the progress of the field as a whole. These advancements have increasing relevance for the energy sector, the development of space materials and engineering applications. In this review, we assess four critical facets of this field: (1) how the current understanding of process variables enhances the electrodeposition of various molten salts and the quality of the resulting product; (2) how the electrochemical setup and the process parameters (e.g., cell reactions) are known to impact the electrodeposition of different metal coatings and refractory-metal coatings; (3) the benefits and drawbacks of non-aqueous molten salt electrodeposition, and (4) promising future avenues of research. The aim of this work is to enhance our understanding of the many procedures and variables that have been developed to date. The expectation is that this review will act as a stimulant, motivating scientists to delve further into the investigation of refractory-metal alloys by utilizing molten salt electrodeposition.

Developing Nonenzymatic glucose biosensors has recently been at the center of attention owing to their potential application in implantable and continuous glucose monitoring systems. In this article, nickel telluride nanostructure with the generic formula of Ni₃Te₂ has been reported as a highly efficient electrocatalyst for glucose oxidation, functional at a low operating potential. Ni₃Te₂ nanostructures were prepared by two synthesis methods, direct electrodeposition on the electrode and hydrothermal method. The electrodeposited Ni₃Te₂ exhibited a wide linear range of response corresponding to glucose oxidation exhibiting a high sensitivity of 41.615 mA cm^–2 mM^–1 and a low limit of detection (LOD) of 0.43 μM. The hydrothermally synthesized Ni₃Te₂, on the other hand, also exhibits an ultrahigh sensitivity of 35.213 mA cm^–2 mM^–1 and an LOD of 0.38 μM. The observation of high efficiency for glucose oxidation for both Ni₃Te₂ electrodes irrespective of the synthesis method further confirms the enhanced intrinsic property of the material toward glucose oxidation. In addition to high sensitivity and low LOD, Ni₃Te₂ electrocatalyst also has good selectivity and long-term stability in a 0.1 M KOH solution. Since it is operative at a low applied potential of 0.35 V vs Ag|AgCl, interference from other electrochemically active species is reduced, thus increasing the accuracy of this sensor.

Non-aqueous electrodeposition entails the process of depositing metals or materials onto electrodes using a solvent or electrolyte that isn't water-based. Researchers have been exploring various techniques such as molten salt, ionic liquids, organic solvents, and deep eutectic solvents for non-aqueous electrodeposition in order to obtain zirconium metal deposition. Our team has directed its attention towards deep eutectic solvents due to their increasing recognition as environmentally sustainable solvents. These solvents boast unique physical and chemical properties, effective dispersal capabilities, high purity, and cost-effectiveness, rendering them suitable for diverse applications. Particularly, they have garnered significant interest in electrodeposition endeavors over the past decade. Despite their advantageous characteristics as electrolytes in electrochemical processes, deep eutectic solvents present challenges such as low conductivity and limited solubility of specific components. Our research has encompassed studies on the solubility of various salts, commonly utilized as supporting electrolytes, alongside zirconium metal salts in deep eutectic solvents, both individually and in combination. We aim to analyze numerous parameters including temperature, pH, ionic strength, and conductivity to determine the optimal composition and parameter settings conducive to zirconium electrodeposition.
