摘要:
本文在室温下采用绿色环保的液相还原法,以乙酸铜和硝酸银为产物前驱体,抗坏血酸为还原剂,β-环糊精为表面活性剂,制备铜银双金属纳米粒子。用X射线衍射仪(XRD)、场发射扫描电子显微镜(FESEM)、能量色散X射线能谱(EDS)、X射线光电子能谱分析仪(XPS)、紫外–可见分光光度计和电化学工作站对样品的结构、微观形貌、光学性质及电催化性质进行了表征。结果表明,随着反应时间的变化制备的铜银双金属纳米粒子的紫外光谱和电催化性能发生相应改变。

Abstract: Cu-Ag bimetallic nanocrystallites were prepared by using a green and convenient approach. In this experiment, ascorbic acid (working as a reducing agent) reduced cupric acetate monohydrate (Cu(CH3COO)2•H2O) and silver nitrate (AgNO3) to Cu-Ag bimetallic particles. X-ray powder diffraction (XRD), field emission scanning electron microscopy (FESEM), energy dispersive spectrometer (EDS) and X-ray photoelectron spectroscopy (XPS) were used to characterize the as-obtained products. The electrochemical properties of Cu-Ag nanocyrstallites were also explored. The results revealed that the as-prepared Cu-Ag could be a promising candidate for wide range of electrochemical applications.
