【摘要】 本文采用循环伏安法研究了FeCl3在五种不同的离子液体(包括疏水性和亲水性的离子液体)中的电化学行为,计算了不同离子液体中FeCl3的扩散系数。实验结果表明:Fe3+在离子液体中的氧化还原过程是一个具有较高可逆性的扩散控制过程。离子液体的阴、阳离子的结构及大小对Fe3+的电化学响应有影响,且离子液体的阴离子的影响较阳离子更大一些。更多还原

【Abstract】 The electrochemical behaviors of FeCl3 in the five ionic liquids(including hydrophilic and hydrophobic ionic liquid)were studied using cyclic voltammetry measurement.This paper also discussed the effect of the cation and the anion of ionic liquid on the electrochemical behavior of FeCl3.At the same time,the diffusion coefficients of FeCl3 in ionic liquids were estimated.The results indicate that the reduction of Fe3+was a reversible process and was controlled by diffusion of FeCl3 in ionic liquids.The structure of the cation and the anion of ionic liquid have affect the electrochemical behavior of Fe3+,and the effect of the anion of ionic liquid is much more larger than the cation.更多还原
