Reduction behavior of cerium (III) ions in NaCl-2CsCl melt

Research output: Contribution to journal › Article › peer-review

Abstract

The cathodic process of cerium (III) ions in NaCl-2CsCl melt was studied by cyclic voltammetry and square wave voltammetry with tungsten and gold electrodes at 873 K. The two electroanalytical methods yield similar results. The cathodic process of cerium (III) ions consists of two reversible steps: Ce³⁺+ e^- = Ce²⁺ and Ce²⁺+ 2e^- = Ce. The half wave potentials of Ce³⁺/Ce²⁺ and Ce²⁺/Ce were determined as -2.525 V vs. Cl₂/Cl^- and -2.975 V vs. Cl₂/Cl^- respectively. The diffusion coefficient of Ce³⁺ was also determined as 5.5 × 10^-5 cm²·s^-1.
