Preparation of copper nanoparticles by chemical reduction of copper(II) complexes in the solid state

چکیده مقاله

Copper nanoparticle are used in different areas such as optoelectronic, catalysis and biological applications. Transition metal complexes, especially the metal compounds of group IB, such as copper(II) causes a change the morphology of the nanoparticles, by varying the chemical reaction method, can alter their catalytic activity. These nanoparticles can be generated in a variety of ways. The methods are included molecular beams, chemical reduction, thermal decomposition of transition-metal complexes and electrochemical synthesis. In this work, Cu nanoparicles have been prepared by reduction of copper(II) complexes. Here hydrazinium sulfate has been used as a reducing agent in chemical reduction of metal complexes. These nanoparticles were characterized by X-ray diffractometer (XRD), IR spectroscopy, scanning electron microscopy (SEM), and EDX analysis.
