The electrochemical behaviors of Li + and Nd 3+ were investigated on W, liquid Sn pool and Sn film electrodes in LiCl-KCl-NdCl 3 melt at 673 K. Various electrochemical techniques, such as cyclic voltammogram, square wave voltammogram, and open circuit chronopotentiometry, were conducted to evaluate the electrochemical behaviors of Li + and Nd 3+ . The reduction of Nd 3+ was found to be a two-step process in the W electrode and a one-step process in the liquid Sn electrode. During the formation of the Nd-Sn intermetallic compounds, only the NdSn 3 would be formed without the reduction of the Li + in the liquid Sn electrode. When the reduction potential moves over −2.77 V vs Cl 2 /Cl − , the Li + in the electrolyte would inevitable be reduced into the liquid Sn electrode. The Nd-Sn intermetallic compounds were deposited on the liquid Sn pool electrode at −2.74 V vs Cl 2 /Cl − in the LiCl-KCl-NdCl 3 melts for 5 h. The products were characterized by SEM-EDS and XRD. The loose product on the surface of the deposition displayed the existence of NdSn 3 in Nd-Sn intermetallic compounds. The high content of Nd inclusion formed by segregation was detected in the solidified Sn electrode.

“…In this work, ternary coating was favored on graphite and Ni-Co-Cu was employed, based on the outstanding performance of binary coatings combining Ni-Co and Ni-Cu in the literature (Solmaz et al, 2008;Solmaz et al, 2009;Demirdelen et al, 2020). Considering the literature, the coating's Co and Cu mole ratios should be kept low in comparison to the Ni mole ratio (Mert and Kardaş, 2011;Sun et al, 2021). The electrodeposition of nickel, cobalt and copper was performed by galvanostatically using Iviumstat Electrochemical Interface with a three-electrode configuration.…”

Energy demand increases with increasing population and industrial developments. Unfortunately, non-renewable sources are used to meet a large portion of the demand. As a result of the negative effects, researchers have begun to investigate renewable sources by working in a variety of fields in order to ensure the energy and humanity's long-term sustainability. Renewable energy sources are very important for the future of the world. In this regard, we can claim that the convenient solution is "hydrogen" which is a promising energy carrier. In this study, alkaline electrolysis system was preferred due to the advantage of being easily integrated with renewable energy sources to meet the power requirements of the system. The platinum (Pt) and stainless steel (SS) electrodes were used as anodes. Graphite (G) and ternary transition metals (nickel, copper, cobalt) modified graphite (G/NiCoCu) electrodes were used as cathode. The modified electrodes were prepared by using a galvanostatic method. The various operation voltages were applied that varied from 2.3V to 3V in order to realize water splitting reaction. The amount of produced hydrogen gas was increased with increasing operation voltage. According to the experimental results, at 3V for 15 minutes of electrolysis time, the produced H 2 gas values were 15 mL, 11.13 mL and 13.12 mL for Pt -G (Cell-1), SS -G (Cell-2) and SS -G/ NiCoCu (Cell-3), respectively.

Alternatives to the widely-used standard anodic decomposition reference electrodes in molten salts are necessary to enable more easily reproduced thermochemical and electrochemical data in molten salt electrolytes. The class of standard reference electrodes called cathodic decomposition electrodes (CDEs) are easily constructed and can be used to make thermochemical measurements in molten salts more directly compared to anodic decomposition electrodes. The lithium eutectic electrode (LEE) was chosen as a sample test case for validation and was applied to thermochemical measurements of electroactive species in molten LiCl-KCl eutectic. Transient measurements were made to measure the Li+ /Li reduction potential at zero current in pure LiCl-KCl eutectic relative to a Li-alloy reference electrode to validate the reference potential of the LEE. Literature-reported electromotive force (emf) measurements against Li-alloy reference electrodes were used to generate a relationship between the LEE and the standard chlorine electrode (SClE) and this relationship was used to evaluate measured and reported formal potential measurements for the LiCl-KCl-GdCl3 system. This work demonstrates the general framework for defining CDEs for any molten salt system and a method for calibrating external reference electrodes against a CDE standard reference electrode, improving the ease of obtaining thermochemical and electrochemical measurements in any molten salt system.
