| Research Abstract |
Electrodeposition of manganese was tried using ionic liquids as solventshaving relatively wide electrochemical windows compared to water. A conventional ionic liquid, 1-ethyl-3-methylimidazolium chloride, however, had the window ranging from 0 to 2 V vs. Mn, that was insufficient for Mn deposition. In contrast, 1-butyl-2,3-dimethylimidazoliumum chloride (1), in which the 2-position of imidazolium cation was substituted, or masked, by methyl group, made possible a reversible deposition/dissolution of Mn on a cyclic voltammerty. Potentiostatic electrolysis using ionic liquid 1 gave a gray amorphous deposit containing manganese. The deposition current efficiency was, however, lower than that reported for aqueous systems.
