Nickel oxide (NiO) and cobalt doped Nickel oxide (Co-NiO) nanoparticles were successfully synthesized by cost effective, environmentally friendly, and scalable eco-precipitation method. The prepared nanoparticles were investigated by X-ray diffraction (XRD), Scanning electron microscopy (SEM), Energy dispersive X-ray analysis (EDAX), Fourier Transform Infrared Spectroscopy (FTIR), Optical spectroscopy (UV) and Cyclic voltammetric (CV). The structural characterization […]
