Synthesis of Cu Nanoparticles

Abstract

The present study concentrates on the synthesis of Cu nanoparticles (CuNPs) using aqueous solution of Polyvinylpyrrolidone (PVP) and tetrachloroaurate by different methods as thermal, sonochemical and electrochemical reduction. As the size of produced nano particles depends on the reaction conditions, we studied the effect of some factors such as the concentration of HCuCl4, the molecular weight of In electrochemical synthesis, the Taguchi method has been used to optimize the three parameters, interval time of synthesis, applied current density and concentration of HCuCl4. Characterization of CuNPs was carried out by Transition electron microscopy (TEM), UV-Vis spectroscopy, and particle size analyser. A large number of nanoparticles with different properties can be fabricated through the various preparation routes such as thermal , chemical, sonochemical, electrochemical , and sonoelectrochemical techniques. A solution of (0, 0.2, 0.4, 0.6 and 0.8) g PVP in 10 ml of deionized water was prepared. After complete dissolution of PVP, (0, 170, 340, 510 and 680 ppm) HCuCl4 was The current density, time of synthesis, and concentration of HCuCl4 as Taguchi factors were studied for investigation of the nanoparticle prepration.The Wing-1 (Standard Data Processing) program was used to determine the particle size of CuNPs.
