简要介绍近3年武汉大学电化学研究中心在熔盐电化学方面的若干研究进展:1)熔盐电解固态化合物制备单质硅及其合金以及无机功能材料;2)适于高温熔盐的全密封长寿命Ag/AgCl参比电极和可负载微量粉末的金属腔(坑)工作电极新技术;3)“三相界线电化学”新概念以及描述三相界线在薄层固态化合物电解还原过程中扩展变化的薄层模型.

Recent research development in molten salt electrochemistry at the Electrochemical Research Centre of Wuhan University is briefly reviewed. Attention is first paid on the preparation of silicon and its binary alloys, as well as oxide based functional materials. In addition, the quartz sealed Ag/AgCl reference electrodes suitable for high temperature molten salts are described. Focus is also given to two types of metal based cavity electrodes that are capable of loading micrograms of oxide powders and hence allow fast and reproducible measurements for the electrochemical behaviour of the powders in molten salts. The article finishes by highlighting the concept of “three-phase interline electrochemistry” in conjunction with reporting the preliminary results from the investigation of a simple "thin layer model" for the electrochemical reduction of solid AgCl in aqueous solution and solid SiO_(2)in molten salts.
