Abstract
Nanoparticles of silver have been prepared by reduction of silver ions in the presence of polymer. In particular, silver nanoparticles were prepared by reduction of silver nitrate in ethanol in the presence of chemical reduction and poly [N-vinylpyrrolidone (PVP)] as a protective agent. The UV-visible spectrum of the material shows a strong plasmon resonance band centered at 402 nm. The band position depends on PVP: silver nitrate weight ratios of silver colloids were influenced by the protective agent was absorbed to the particle surface. The rate constant remarkably depends in a first order on PVP : AgNO3 weight ratios and reaction temperature.
