Nanoparticles Ni and NiO: Synthesis, characterization and magnetic properties

Abstract

The present investigation reports, the novel synthesis of nanoparticles Ni and NiO using thermal decomposition and their physicochemical characterization. The nanoparticles Ni powder have been prepared using [bis(2-hydroxyacetophenato)nickel(II)] as precursor. Transmission electron microscopy (TEM) analysis was demonstrated nanoparticles Ni with an average diameter of about 14–22 nm. The products were characterized by X-ray diffraction (XRD), TEM, high-resolution transmission electron microscopy (HRTEM) and Fourier transform infrared (FT-IR) spectroscopy. The magnetic property of Ni and NiO was studied with vibrating sample magnetometer (VSM).
