摘要：首次以铝箔代替恒电位/电流仪惰性电极作为基体,采用辅助电极电沉积法成功制备了氧化铜纳米颗粒。用X射线衍射仪和透射电子显微镜对所制备的纳米粉体进行了表征,结果表明:氧化铜纳米颗粒为球形,粒径为50nm左右,颗粒大小均匀,形态稳定。并且与氧化还原法和研究电极电沉积法进行了比较。

Abstract：Potentiostat／galvanostat is used to electrodeposit CuO nanoparticles with a piece of aluminum foil substitutes for Ptelectrode as it used to be．XRD and T EM are used to detect the composition size and morphology of the nano-particles．T he results show that CuO nano-particles are uniform with size about 50nm and the morphology is global．And a contrast with the ordinary reduction-oxidation reaction and working electrode electrodeposition method is made．
