Transient Electrochemical Process of Nb(V) in FLINAK Melt

摘要: 采用记时电流法和记时电位法对5价铌Nb(V)在FLINAK熔盐中的氧化-还原过程进行了研究。结果表明,Nb(V)(K₂NbF₇)在FLINAK熔盐中的电化学还原经历一个电化学-化学-电化学反应(ECE)途径。Nb(V)在FLINAK熔盐中的还原反应是单电子和4电子两步电化学反应过程。

Abstract: The redox process of Nb(V) in (K₂NbF₂) in FLINAK melt has been by studied using chronopotentiometry and chronoamperometry. The results show that the electrochemical reduction of Nb(V) in FLINAK melt goes through an electrochemical-chemical-electrochemical reaction(ECE) process. The electrochemical reaction of Nb (V) in FLINAK melt is a mono-electron and four-electron transfer process.
