Role of ionic liquids in the electrodeposition of metals

Abstract

Green chemistry techniques have gained significant importance in advancing chemical engineering and processes in the modern era, contributing to the implementation of sustainable development strategies. Ionic liquids (ILs) at room temperature have emerged as versatile solvents in catalysis, separation science, and electrochemistry. Conventional synthesis of ILs typically involves a two-step process using refluxing solvents, which is time-consuming and requires large amounts of organic solvents. This study investigates the synthesis of alkylmethylimidazolium salts by the co-heating of haloalkanes and 1-methylimidazole, highlighting the role of ILs in green chemistry, particularly in the electrodeposition of metals. The objective of this research is to explore the impact of ILs on the electrodeposition process, aiming to develop environmentally friendly and efficient metal deposition methods. The methodology involves the preparation of ILs through a facile and sustainable approach, followed by the characterization of their physicochemical properties. The ILs are then utilized as electrolytes for metal electrodeposition, and the resulting metal films are analyzed for their morphology, structure, and properties. The findings of this study demonstrate the significant influence of ILs on metal electrodeposition. The ILs exhibit excellent solvation properties, facilitating the reduction and deposition of metals with improved control over morphology and structure. Additionally, the ILs offer the advantage of reduced environmental impact compared to traditional organic solvents. The main innovation lies in the application of ILs as green solvents in metal electrodeposition, contributing to the development of sustainable and efficient processes in the field of green chemistry.
