One Pot Synthesis of Crystalline Silver Nanoparticles

Abstract

This paper describes a simple and convenient procedure for the preparation of crystalline silver nanoparticles. One pot synthesis of silver nanoparticles free from stabilizing agent has been investigated. Aqueous solution of AgNO3 has been reduced by N2H4.H2O in presence of CH3COONa. The aggregation of silver nanoparticles were prevented by CH3COONa in chemical bath and then washed away, leaving crystalline silver nanoparticles. The whole experiment has been carried out at room temperature, using water as solvent and also within very less time. The particles synthesized were characterized by UV-Visible, FTIR, TGA, TEM & X-ray diffraction studies.
