Microwave assisted synthesis of silver nanorods

Abstract

Silver nanoparticles have unique and distinctive properties like optical, electrical and conductive properties. These properties of nanoparticles depend on their size, shape and crystalinity. There has been a lot of work published on synthesis of silver nanoparticles with controlled morphology. However, there has not been much work done on silver nanoparticles with controlled morphology, high yield and less reaction times. The aim of this research is to synthesize silver nanowires with high yield at low reaction timings. In order to achieve this, different salts like NaCl, KCl, MgCl2, CaCl2, MnCl2, CuCl2 and FeCl3 where used. The effect of salt on the silver nanowires is evaluated by using SEM images. In addition , effect of concentration of salt on yield of silver nanowires and a novel method for the continuous flow synthesis of silver nanoparticles have been studied. Characterization of silver nanoparticles has been done using SEM, TEM and optical microscopy.
