Synthesis of Monodispersed Lauric Acid Capped Silver Nanoparticles by Wet-Chemical Reduction Method

Abstract:

Silver nanoparticles with narrow distribution were prepared by a simple route in water in presence of lauric acid as the capping agents. The morphology and crystal structure of as-synthesized silver nanoparticles were analyzed by transmission electron microscopy (TEM) and X-ray powder diffraction (XRD). The mass ratio of lauric acid and silver nitrate, the reaction temperature play important roles on the morphology and size of the silver nanoparticles. Well-dispersed silver nanopartilces with diameter of 8 nm were obtained when the mass ratio of lauric acid and silver nitrate was 1.2:1 and the reaction temperature was room temperature. It is also confirmed that the sol system was monodisperse nanosilver sol.
