All the physical and chemical properties are size dependent and the properties of the materials on the nanosize scale have important consequences in wide ranging fields. This paper reports the electrochemical synthesis of silver nanoparticles. The size of the synthesized nanoparticles was found to be influenced by the variation in the current density as well the nature of the tetra alkyl ammoniumsalts used as capping agents. Thus silver nanoparticles of varying sizes could be synthesized. These are characterized using XRD, XPS and TEM techniques.
