研究了钴在离子液体-1-正丁基-1-甲基吡咯吡啶双（三氟甲基磺酰基）亚胺中的电沉积。当温度升高到200℃时，Co的过电位明显降低，这可能是由于Co的配位环境发生了变化。丙酮的加入导致过电位降低，表明Co阳离子与丙酮的选择性配位提高了电荷传递速率。离子液体中的电荷转移和晶体生长受到溶解金属的配位环境和双电层结构的影响。(c) 2007电化学学会。
The electrodeposition of cobalt was investigated in an ionic liquid, 1-n-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl) imide. The overpotential for the electrodeposition of Co was reduced remarkably by elevating the temperature up to 200 degrees C, probably due to the change in the coordination environment of Co species. The addition of acetone led to the decrease in the overpotential, indicating the selective coordination of Co cation with acetone enhanced the charge transfer rate. It has been suggested that the charge transfer and crystal growth in the ionic liquid are affected by the coordination environment of the dissolved metal species and the structure of electric double layer.
