A Synthesis of Copper Nanoparticles by Electrochemical Method

Abstract

This article presents an eco-friendly, simple, and costly effective electrochemical method of copper nanoparticlefor LearningMedia.Copper nanoparticles were synthesized by Plating & Nano-Synthesis Kit, using L-ascorbic acid and curcumin as a reducing agent and stabilizer, respectively. The applied voltage of 12.0 V, electrode distance of 1.0 cm and curcumin volume of 2.0 ml, respectively were obtained as the optimums synthesis conditions. The colloidal copper nanoparticles were characterized by Tyndalleffect and UV-visible spectrophotometry. The UV-visible spectroscopic analysis showed the maximum absorbance wavelength (_max) of 595 nm. The obtained powders were characterized by X-ray diffraction (XRD), and scanning electron microscope (SEM), which indicated the 250-300nm diameter and spherical particle shape of copper nanoparticles.
