Preparation of colloidal silver nanoparticles by chemical reduction method
Song KC, Lee SM, Park TS, Lee BS
Colloidal silver nanoparticles were obtained by chemical reduction of silver nitrate in water with sodium borohydride (NaBH4) in the presence of sodium dodecyl sulfate (SDS) as a stabilizer. The obtained nanoparticles were characterized by their UV-vis absorption spectra and transmission electron micrograph (TEM) images. The UV-vis absorption spectra showed that NaBH4 served not only as a reducing agent but also as a stabilizer, which protects the aggregation of silver nanoparticles. The TEM images showed that the particles were dispersed better with increasing the NaBH4 concentration.
Keywords: Silver Nanoparticles; Chemical Reduction; SDS; UV-vis Absorption Spectra; TEM
