Abstract

The electrochemical method is efficient, cost effective, and environmentally friendly process. Copper nanopowder has been known, as a nontoxic, inexpensive, highly conductive, excellent microbial agent, catalytic, and sensors applicable. Copper nanopowder was prepared by an electrochemical method under various conditions. The effect of type and concentration of electrolyte solution, and the sample treated with thiourea and ascorbic acid on the size and purity of copper nanopowder was investigated. Two different salts copper: sulfate and nitrate aqueous solutions (CuSO4.5H2O), Cu(NO3)2.5H2O were used to produce copper nanopowder. The synthesized copper nanopowder was identified using X-ray diffraction (XRD), the scanning electron microscope (SEM), and Energy Dispersive Spectrum (EDS). The results of XRD patterns revealed a high degree of crystallinity, monophasic nature, and pure copper powder with no impurities or oxides observed for both electrolyte solutions after treated with 2 percent of ascorbic acid. It was confirmed that particle size at room temperature was as small as 25nm when the copper nitrate is used as an electrolyte solution compared to copper sulfate (41nm).

Summary

Introduction

The synthesis of metal Nanopowders has being given considerable attention due to their unique physical and chemical properties. Nanoparticles possess a high surface-to-volume ratio owing to their small size. This feature has attracted many researchers to widely investigate nanomaterials and their applications. Metallic nanoparticles have been vastly used for numerous applications, such as catalysis, solar energy, optical, magnetic, thermal, biological sensors, synthesis of chemical composite, and medicine [1,2,3]. Several methods have been utilized to prepare the metallic Nanopowder, such as chemical, physical, and biological reduction methods. Each one of these synthesis methods has advantages and disadvantages in producing metallic nanopowder. Electrochemical deposition technique is among the most important appropriate, simple, fast, high throughput, and economical methods which are used for a diversity of materials including copper nanopowder[4, 5]
