    • 本論文探討使用氯化鋅-氯化-1-乙基-3-甲基咪唑(zinc chloride-1-ethyl-3- methylimidazolium chloride;ZnCl2-EMIC)離子液體電沉積鋅與鈀/鋅合金，共分為兩部份：(一)將氯化鋅-氯化 1-乙基-3-甲基咪唑添加入EMI-BF4中，探討其成核反應與不同濃度對所得之鋅鍍層的形貌與性質的影響，(二)添加氯化鈀（PdCl2）至氯化鋅-氯化 1-乙基-3-甲基咪唑離子液體中，探討電沉積鈀/鋅合金奈米線與性質。利用定電位階升(chronoamperometry)法發現Zn(II)在70℃的玻璃碳電極還原成Zn(0)的成核機制為瞬時成核。在不使用模版的輔助及未施予攪拌的條件下，利用定電位方式進行電沉積，當施以足夠的過電位方式時，可獲得沿著基材垂直生長的鈀/鋅合金奈米線結構，利用置換反應與氧化剝削方式可以調控鈀/鋅奈米線中鈀對鋅的比例，其電沉積過程主要是以擴散控制成長，而電沉積所得之鈀/鋅合金奈米線可應用在乙醇催化。電沉積樣品之表面形貌、成份與晶形結構是以掃描式電子顯微鏡(SEM)、能量分散光譜儀(EDS)、X光繞射分析儀(XRD)與穿透式電子顯微鏡(TEM)進行分析鑑定。

    In this study, zinc chloride-1-ethyl-3-methylimidazolium chloride(ZnCl2-EMIC) ionic liquid has been used to electrodeposit (a) Zn from ZnCl2-EMIC diluted with EMI-BF4, and (b) PdZn alloy from ZnCl2-EMIC ionic liquid containing PdCl2. The morphologies of the Zn and PdZn alloys were examined with scanning electromicreoscopy(SEM), energy dispersive X-ray spectroscopy(EDS), X-ray diffraction(XRD) techniques, and Transmission Electron Microscope(TEM).
    Chronoamperometric results indicate that the deposition of Zn(II) on the GC electrode involved with a three-dimesional instantaneous nucleation/growth process at 70℃. Direct template-free electrodeposition of aligned PdZn nanofilaments was achieved on a tungsten substrate in a quiescent Lewis acidic ZnCl2–EMIC ionic liquid containing PdCl2 at 110 ℃ by applying an extremely large deposition overpotential. The Zn content in the PdZn alloy could be decreased by diaplacement reaction or anodic stripping. It is found that PdZn nanofilaments exhibit excellent catalytic activity for ethanol electrooxidation.
