Abstract
Ionic liquids, as a novel class of green solvents and functional materials, exhibit unique advantages in the field of electrochemical synthesis. Traditional organic solvents are associated with issues such as volatility, flammability, and environmental pollution, whereas ionic liquids possess characteristics such as low volatility, high thermal stability, and tunable properties, providing an ideal reaction medium for electrochemical synthesis. This study aims to systematically evaluate the application performance of ionic liquids in electrochemical synthesis by selecting typical electrochemical reaction systems and employing electrochemical testing methods such as cyclic voltammetry and chronoamperometry, combined with quantum chemical calculations. The research delves into the influence of different structural ionic liquids on the kinetics, selectivity, and yield of products in electrode processes. The results indicate that specific cation-anion combinations of ionic liquids can significantly enhance electrode surface properties, improve catalytic activity, and broaden the electrochemical window, achieving efficient synthesis of target products under mild conditions. Compared with traditional solvent systems, the optimized ionic liquid system increased the yield of target products by more than 30% while reducing the likelihood of side reactions. This study not only elucidates the intrinsic relationship between the structure of ionic liquids and their electrochemical performance but also provides theoretical foundations and technical support for the development of high-performance electrochemical synthesis processes, promoting the practical application of green chemistry concepts in the field of electrochemistry.
