Comparative Morphological Studies on NiO, CoO and Fe2O3 Nanoparticles

Abstract

Stable oxides of Ni, Fe and Co nanoparticles are synthesized by chemical route using leaf extraction. Structural, biological morphological and magnetic properties were investigated. X ray pattern shows a polycrystalline structure of samples. Diffraction planes of (200), (122) and (200)-oriented crystal structures were revealed by X-ray pattern for NiO, Fe2 O3 and CoO respectively. Hexagonal, orthorhombic and cubic crystal structures have been revealed respectively for NiO Fe2 O3 and CoO nanoparticles. Microscopic structure has been detected by using of Scanning Electron Microscopy. Ni, Fe and Co is present at 71%, 78.8%, 79% as indicated by EDS analysis respectively. Mass magnetization values of 51, 61 and 54 emu/g are recorded for NiO, Fe2 O3 and CoO nanoparticles.
