应用循环伏安和交流阻抗法研究有机溶剂二氯甲烷对二茂铁在离子液体1-丁基-3-甲基咪唑六氟磷酸盐(Bm imPF6)中电化学行为的影响.实验表明,二氯甲烷可促进离子液体的离子解离,减小离子液体粘度,增加离子液体电导率,加速二茂铁在离子液体中的扩散,增大氧化还原峰电流.由于电极界面双电层结构的变化,导致双电层电容增大,电极反应电阻减小,从而加速了界面电子传递反应.
Cyclic voltammetry and electrochemical impedance spectroscopy were used to study the effect of organic solvent dichloromethane on the electrochemical behavior of ferrocene in ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate (Bm imPF6) .Experiments showed that bis Chloromethane can promote the ionic dissociation of ionic liquids, reduce the viscosity of ionic liquids, increase the conductivity of ionic liquids, accelerate the diffusion of ferrocene in ionic liquids, and increase the redox peak current. Due to the change of the electric double layer structure , Resulting in double-layer capacitance increases, the electrode reaction resistance decreases, thus accelerating the interface electron transfer reaction.
