The electrochemical reduction of Ce(III) on the W electrode was studied in the LiCl-KCl-CeCl3 molten salt at temperature of 753 K, cyclic voltammetry (CV) curves were employed to investigate the electrochemical behavior of Ce(III) on the W electrode immersed in the absence (black curve) and presence (red curve) of CeCl3 (Fig. 1a). Only a pair of redox peak (A/A') was appeared around −2.50 V/−2.45 V in the black solid line, corresponding to the redox couple of Li(I)/Li(0). After the addition of

摘要：
In order to improve the utilization of spent fuel, molten salt electrolysis is used to separate lanthanides from spent fuel. The electrochemical reduction mechanism of Ce(III) ions and dynamic properties of Ce(III)/Ce(0) were provided in the LiCl-KCl molten salt by diversified electrochemical techniques. The diffusion coefficient of Ce(III) and the exchange current densities of Ce(III)/Ce(0) on the W electrode were calculated by cyclic vol-tammetry and linear polarization, and the reaction activation energy was calculated to be 30.8 kJ center dot mol-1. The electrochemical behaviors were measu...
