Transient Electrochemical Process of Nb(V) in FLINAK Melt

摘要: 采用記時電流法和記時電位法對5價鈮Nb(V)在FLINAK熔鹽中的氧化-還原過程進行了研究。結果表明,Nb(V)(K₂NbF₇)在FLINAK熔鹽中的電化學還原經歷一個電化學-化學-電化學反應(ECE)途徑。Nb(V)在FLINAK熔鹽中的還原反應是單電子和4電子兩步電化學反應過程。

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.
