在惰性氩气保护下，以水/乙腈混合溶剂为溶剂，通过硼氢化物还原硝酸铜盐，成功地合成了铜纳米粒子。通过在制备纳米铜颗粒的过程中引入乙腈并防止氧化，首次大规模制备了纳米铜颗粒。采用紫外-可见吸收光谱、透射电子显微镜（TEM）、X射线光电子能谱（XPS）和X射线衍射（XRD）等技术对纳米粒子进行了表征。高分辨率TEM照片显示形成了尺寸小于100 nm的均匀的纳米铜颗粒。与柠檬酸盐保护的铜纳米粒子相比，这种新的合成方法显示出优异的稳定性，这可能为改善铜纳米粒子的结构和尺寸的微调提供一种有效的途径。(C)2009 Elsevier B. V.保留所有权利。
Copper nanoparticles were successfully synthesized by the borohydride reduction of copper nitrate salt in water/CH3CN mixed solvent under inert argon-purged conditions. Cu nanoparticles were synthesized in large-scale production for the first time by introducing CH3CN into water and preventing oxidation during the preparation of nanoparticles. Nanoparticles were characterized by using UV-visible absorption spectroscopy, transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and X-ray diffraction (XRD) techniques. High resolution TEM Pictures showed the formation of homogeneous cubic-structured copper nanoparticles with sizes less than 100 nm. This new kind of synthesis method shows the excellent stability compared with that of citrate-protected copper nanoparticles, which may provide an efficient way to improve the fine tuning of the structure and size of copper nanoparticles.
