Summary: The electrochemical behavior and electrodeposition of indium in an electrolyte composed of 0.1 mol/L InCl3 in [Py-1,Py-4]TFSI were studied on a gold electrode. The results revealed complex electrochemical behavior with multiple reduction and oxidation peaks. In situ XPS analysis showed that In(I) was the intermediate species during the reduction process. The presence of Cl- oxidation was also observed in the anodic regime.

Summary: In this study, a mathematical model is developed to investigate the influence of process parameters on the anode effect during neodymium and didymium oxide electrolytic reduction. The anode effect is caused by bubble coverage and limitations on the mass transfer of oxide species, with variables such as current density, oxide content, viscosity, and electrolyte composition playing a significant role in the anodic process.

Summary: The recycling of materials may introduce ruthenium into the copper electrowinning process, causing potential ruthenium losses. This study explores the oxidation behavior of ruthenium in copper electrowinning and finds that ruthenium is not directly oxidized to ruthenium tetroxide electrochemically. Instead, the formation of oxidants through chemical reactions leads to the conversion of ruthenium compounds to highly volatile ruthenium tetroxide. The temperature and anodic potential play significant roles in these reactions.

Summary: This study investigated the impact of rare earth oxide (REO) concentration on the deposition process and selective recovery of the metal being deposited in a molten fluoride salt system. By constructing a phase diagram and using different deposition techniques, co-deposition of neodymium and praseodymium was achieved, leading to higher co-deposition rates and a more effective deposition process.

Summary: Al-V alloys were synthesized by potentiostatic electrodeposition on a glassy carbon electrode, resulting in the formation of Al3V and AlV3 alloys through solid-state interdiffusion. Control of vanadium ion concentration in the electrolyte allowed for regulation of alloy composition and surface morphology. This research suggests that controlled co-deposition of aluminum and vanadium could lead to the successful development of advanced Al3V and AlV3 alloy synthesis technology.

Summary: The main goal of this research was to electrodepose and characterize novel ceria-doped Zn-Co composite coatings. It was found that the use of ceria sol improved the corrosion resistance of the coatings, transforming them from a cauliflower-like morphology to a uniform and compact coral-like structure, and exhibited a good self-healing rate in a chloride-rich environment.

Summary: The study investigated the electrochemical decomposition of spent catalyst in molten salts for the extraction of precious metals, focusing on aluminum electrowinning from xLiF-(1-x)AlF3 melts. The results revealed a diffusion-controlled two-step process with both one-electron and two-electron reductions occurring simultaneously at close potentials. Further research is needed to optimize the process parameters for aluminum reduction during catalyst treatment and primary metal production.

Summary: The electrodeposition processes of neodymium and praseodymium were studied in molten electrolytes, showing that constant praseodymium deposition overpotential is crucial for achieving high deposition current densities. Various electrochemical techniques were applied to understand the reduction mechanisms of Nd and Pr ions on different cathodes, providing valuable insights for environmentally friendly rare earth metal deposition and recycling of neodymium-iron-boron magnets.

Summary: The morphologies of metal powders produced by electrolysis are correlated with their crystal structure, which is influenced by exchange current density and overpotential for hydrogen evolution reaction. Decreasing exchange current density can change crystal structure of powder particles from preferred orientation in dendrites to randomly oriented crystallites in spherical particles. Processes involving molten salt electrolysis and deep eutectic solvents are also discussed in this review.
