本研究以氧化锌为锌源，研制了一种新型电解液尿素/1-乙基-3-甲基咪唑氯化物以取代传统的硫酸电镀锌工艺。用计时电流法和循环伏安法研究了氧化锌在尿素/1-乙基-3-甲基咪唑氯化铵电解液中的电化学行为。该电解液的循环伏安曲线表明，锌的还原是一个扩散控制的不可逆过程，通过一步两电子转移过程。计时电流测量表明，在353K时，锌在钨电极上的电沉积遵循扩散控制生长模型的三维瞬时成核过程。用不同的表征技术对计时安培测量得到的电沉积进行了分析。扫描电子显微镜照片显示，在较低的阴极电位下，电沉积层呈片状，而在较负的阴极电位下，则形成簇状结构。经X射线衍射仪和能谱分析证实，所得电镀层为金属锌。©日本电化学会，版权所有。
In this study, a new electrolyte urea/1-ethyl-3-methylimidazolium chloride was developed to replace traditional sulfuric acid in the zinc electroplating process using zinc oxide as a zinc source. The electrochemical behavior of zinc from zinc oxide was investigated in the urea/1-ethyl-3-methylimidazolium chloride electrolyte using chronoamperometric and cyclic voltammetric techniques. The cyclic voltammograms for this electrolyte illustrated that the zinc reduction is a diffusion–controlled irreversible process via a single-step two-electron transfer procedure. Chronoamperometric measurements suggested that the zinc electrodeposition on a tungsten electrode followed a three-dimensional instantaneous nucleation with a diffusion-controlled growth model at 353K. Electrodeposits from Chronoamperometric measurements were analyzed with various characterization techniques. SEM images show that electrodeposits were flakes-like at low cathodic potentials and became clusters at more negative cathodic potentials. The obtained electrodeposits are metallic zinc, confirmed by XRD and EDS. © The Electrochemical Society of Japan, All rights reserved.
