Abstract

Silver nanoparticles are prepared by a chemical reduction method, using silver nitrate as the metal precursor and sodium borohydride as the reducing agent. Polyvinylpyrrolidone and 1,2-dimethoxy-ethane are used as stabilizing ligands on the surface nanoparticles. The silver nanoparticles obtained with this method are shown to exhibit typical surface plasmon absorption behavior at about 400 nm, and transmission electron microscopy and dynamic light scattering show that the average size of silver nanoparticles is between 30–50 nm, depending on the chemical procedure and the stabilizer used. The effect of hydrogen peroxide as the oxidant and hydrazine as the reducing agent is studied in conjunction with methylene blue dye. It is demonstrated that the chemical surface modification has great influence on silver nanoparticle reactivity.
