The Preparation of Size-Controlled Antimony Nanoparticles by Electrochemical Method
This paper prepared some antimony nanoparticles with different particle size by electrochemical method. A method of preparing size-controlled antimony nanoparticles was established in the hydrochloric acid solution, which alkyphenol ethoxylates emulsifier was used as surface dispersants by electrochemical technology based on the optimization of the preparation technology. Those obtained antimony nanoparticles was characterized and analyzed by means of transmission electron microscopy (TEM), Fourier transform infrared absorption spectrum (FT-IR), X-ray diffraction (XRD). The experiment results show that alkyphenol ethoxylates emulsifier can effectively coat on the surface of antimony nanoparticles, current density and electrolysis time have an important influence on the particle size of those obtained antimony nanoparticles. When the current density is 25mA/cm2 and electrolysis time is 30minutes, spherical antimony nanoparticles with an average diameter of 12nm and good dispersion can be prepared.
