摘　　要：采用循环伏安法(CV)研究了二价铜离子在1-丁基-3-甲基咪唑醋酸盐[C_(4)C_(1)Im][OAc]离子液体中的氧化还原过程及电化学行为。实验结果表明:[C_(4)C_(1)Im][OAc]离子液体的电化学窗口为3.3 V;铜离子在[C_(4)C_(1)Im][OAc]中的氧化还原为非可逆过程,铜离子还原过程受扩散传质控制,由Cu^(2+)→Cu^(+)、Cu^(+)→Cu^(0)的扩散系数分别为0.0009394,0.001752 cm^(2)/s,SEM及XRD分析表明铜离子在醋酸盐离子液体中可以被沉积出来。The electrochemical behavior and the oxidation-reduction of copper ion was investigated by cyclic voltammetry(CV)in the 1-butyl-3-methyl imidazolium acetate[C_(4)C_(1)Im][OAc]solvent system.The results showed the electrochemical window of[C_(4)C_(1)Im][OAc]was up to 3.3 V.The redox process of copper ion in[C_(4)C_(1)Im][OAc]was irreversible.The two reduction reactions of copper ions(Cu^(2+)→Cu^(+),Cu^(+)→Cu^(0))were controlled by diffusion.The diffusion coefficients of the steps were 0.0009394 cm^(2)·s^(-1)and 0.001752 cm^(2)·s^(-1),respectively.SEM and XRD showed that copper ions in acetate-based ionic liquids could be successfully deposited.
