摘要
采用电化学方法制备银纳米粒子,选择十二烷基苯磺酸钠(SDBS)作为纳米粒子稳定剂,建立了在水相中应用电化学手段获得粒径可控的球状银纳米粒子的方法,并讨论了SDBS在此过程中可能的作用机理。应用旋转电极系统,研究搅拌方式、电解时间、旋转速度和电解电流等主要实验参数对所得产物粒径和单分散性能的影响。并用X射线衍射(XRD)和扫描电子显微镜(SEM)对所得银纳米粒子进行表征。
A novel electrochemical method for synthesis of size-continUed silver nanoparticle in the aqueous phase under the protection of sodium dodecyl benzene sulfonate (SDBS) was established, which was ther used as the stabilizer for the silver clusters. The protective mechanism of SDBS in the electrochemical synthesis of silver particles was also discussed. A rotating electrode system was used to study the effect of several key experimental parameters such as stirring mode, electrolysis time, rotation speed and electrolysis current on particle size and distribution. The obtained silver nanoparticles were characterized by means of powder X-ray diffraction (XRD) and scanning electron microscope (SEM).
