Synthesis and characterization of copper doped cobalt oxide (Co3O4) by co-precipitation method

Abstract

Today nanomaterials play a key role in various fields such as electronics, aerospace, pharmaceutical sand biomedical because of their unique, physical, chemical and biological properties which are different from bulk materials. In this research work, we have reported a co-precipitation method used to synthesize the copper doped cobalt oxide nanoparticles. The characterization of nanoparticles were investigated by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) to determine the structural properties and particle size respectively. By XRD analysis, we confirm that Co3O4 nanoparticles are formed and mean grain size is decreased with increasing Cu doping (from 18 to 12 nm).
