Abstract:

A novel electrochemical method for synthesis of sizecontrolled 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).

Key words: silver nanoparticle; sizecontrolled; electrochemical method; sodium dodecyl benzene sulfonate
