摘要分析了三种不同的非水钯电解液的密度、粘度、电导率和循环伏安等物理和电化学特性。循环伏安行为显示出典型的还原和氧化峰，对应于所用电解液中钯的沉积和剥离。研究了从氯化胆碱/乙二醇(ChCl-EG)、氯化胆碱/尿素(ChCl-尿素)和1-丁基-3-甲基咪唑氯-四氟硼酸盐(BMIM-Cl-BF4)溶液中电沉积钯薄膜。采用恒电流电解法可获得致密的镀层。沉积物的扫描电子显微镜显示主要是结节状的Pd颗粒。
Abstract The physical and electrochemical characteristics such as density, viscosity, electrical conductivity and cyclic voltammetry of three different non-aqueous palladium electrolytes were analysed. The cyclic voltammetry behaviour showed typical reduction and oxidation peaks corresponding to the deposition and stripping of palladium in the electrolytes employed. The electrodeposition of palladium films from choline chloride/ethylene glycol (ChCl-EG), choline chloride/urea (ChCl-urea) and 1-butyl-3-methylimidazolium chloride-tetrafluoroborate (BMIM-Cl-BF4) solutions was demonstrated. Compact deposits were obtained with galvanostatic electrolysis. The scanning electron micrographs of the deposits revealed predominantly nodular Pd particles.
