This analysis reveals the exchange current density and transfer coefficient of molybdenum in NaCl-KCl melts, suggesting important electrochemical properties.
In this study, the exchange current density and the transfer coefficient of molybdenum in NaCl-KCl molten salt were accurately obtained using Tafel plot and linear polarization. The exchange current density for Mo0/Mo3+ redox couple was found to be 74 ± 0.7 mA/cm2 at 720 °C and 4.5 wt. % MoCl3. The cathodic transfer coefficient was measured to be 0.7 ± 0.02. The concentration dependence of the exchange current density was also investigated. The diffusion coefficient was determined to be 8.052 · 10–5 cm2/s and 4.012 · 10–5 cm2/s by linear and square wave voltammetry, respectively.
