Abstract

The electrochemical behaviors of divalent iron species were investigated in a room-temperature molten salt (RTMS) consisting of 1-n-butyl-1- methylpyrrolidinium cation (BMP⁺) and bis(trifluoromethylsulfonyl) imide (TFSI^-) anion. The TFSI^--salt of Fe(II) was soluble in BMPTFSI at room temperature. The cyclic voltammetric data for the Fe(III)/ Fe(II) processes at 1.1 V vs. Ag/Ag(I) showed quasi-reversible kinetics on a platinum electrode. The diffusion coefficient of Fe(II) determined by chronoamperometric techniques was 9.7 × 10^-8 cm² s^-1 at 25°C. After cathodic reduction of Fe(II) at - 2.0 V, furthermore, metallic Fe was electrodeposited on a copper substrate.
