研究了以空灵溶液电沉积铁（Fe）的方法。溶液由氯化亚铁（FeCl2）、二lyme （G2）和氯化铝（AlCl3）组成，其中铁的种类估计为[Fe(G2)2]2+络合阳离子。通过比较常见的水溶液电解质，确定了氢气析出对铁镀层形貌的影响。用FeCl2-G2-AlCl3bath制备了一种不受氢气析出影响的Fe薄膜，用瞬时成核机制解释了Fe的成核。结果表明，与水电解质和其他非水电解质相比，Fe薄膜的表面形貌致密而光滑。
Electrodeposition of iron (Fe) from an ethereal solution was investigated. The bath consisted of ferrous chloride (FeCl2), diglyme (G2), and aluminum chloride (AlCl3), in which iron species were estimated to be [Fe(G2)2]2+complex cations. The effect of hydrogen gas evolution on the morphology of iron deposits was determined by comparing common aqueous electrolytes. An Fe thin film was fabricated using the FeCl2–G2–AlCl3bath without the influence of hydrogen gas evolution, and the nucleation of Fe was explained by an instantaneous nucleation mechanism. As a result, the surface morphology of the Fe thin film was compact and smooth compared with the cases of aqueous and other nonaqueous electrolytes.
