离子液体中电沉积金属镍的研究
Study on Electrodeposition of Pure Nickel
本文以NiCl2与氯化1-乙基-3-甲基咪唑（EMIC）、乙二醇（以下简称EG）为主盐体系研究了离子液体中镍的电沉积。当EMIC/NiCl2/EG的摩尔比为2:1:6～2:1:9时，能够得到银灰色或者银白色金属镍的镀层；在EMIC/NiCl2/EG熔盐中加入0.2~0.4g/L丁炔二醇时，能够有效地提高镍镀层的外观质量；从SEM照片可以看出，电流密度在40~80A/dm2范围内，金属镍的结晶细小而致密；XRD分析表明，镍的结晶为面心立方结构。
he electrodeposition of Ni from a 1-ethyl-3-methylimidazolium chloride (EMIC) and ethylene glycol (EG) ionic liquid containing NiCl2 was investigated. silver gray or silver white electrodeposits were obtained while the mole ratio of EMIC/NiCl2/EG was 2:1:6～2:1:9. Addition of butynediol into EMIC-NiCl2-EG bath resulted in remarkable improvement of the appearance. SEM images of electrodeposits showed that the crystalline of metallic nickel was small and dense while current density was 40-80A/dm2. X-ray diffraction (XRD) indicates that the obtained electrodeposits was fcc polycrystal structure.
