摘要：

The 1-butyl-3-methylimidazolium hexafluorophosphate([BMIM]PF6) ionic liquid was synthesized by 1-Chlorobutane, N-Methylimidazole and KPF6. The structure of ionic liquid was investigated by infrared (IR) spectrum. The electrochemical windows of [BMIM]PF6 and the electrochemical behaviors of Ce(III) in [BMIM]PF6 containing ethylene glycol (EG) and CeCl3([BMIM]PF6-EG-CeCl3) were studied by cyclic voltammetry. The results indicated that the electrochemical window of [BMIM]PF6 was 4.0 V and the electrodeposition of Ce(III) from [BMIM]PF6-EG-CeCl3 was controlled by diffusion and irreversible growth process at 80°C. The cathodal transfer coefficient (α) and diffusion coefficient (D0) of Ce(III)in [BMIM]-PF6-CeCl3-EG were: α=0.05, D0=2.45×10-6 cm2·s-1. The surface morphology of Ce electrodeposited on copper foil was characterized by means of scanning electron microscopy (SEM). The results indicated that the size of electrodeposit increased with cathodic potentials increasing. The composition of Ce was analyzed by energy dispersive spectroscope (EDS) and the results indicated that the surface electrodeposit was pure cerium and its oxide.
