Abstract

Spinel Co 3 O 4 nanoparticles smaller than 10 nm were effectively produced in this study using a Co-precipitation method under optimal conditions. The as-synthesized Co 3 O 4 nanoparticles were found to have great purity and a cubic Co 3 O 4 phase structure with good crystallinity and crystallite size of approximately 9.3 nm, as determined by X-ray diffraction investigation. The Transmission Electron Microscope and Scanning Electron Microscope definitively verified the spherical nanoparticle structure with high density and consistent orientations. The high-resolution-TEM investigation revealed that the produced spinel Co 3 O 4 nanoparticles are single-crystalline and free from observable imperfections. The HR-TEM results indicated that Co 3 O 4 nanoparticles exhibit distinct lattice fringes that correspond to the interplanar spacings identified in the XRD investigation. The energy-dispersive X-ray spectroscopy …
