Synthesis and characterizations of NiO nanoparticles via solid-state thermal decomposition of nickel(II) Schiff base complexes

摘要

To raise the need of new precursors in the synthesis of NiO nanoparticles, mononuclear nickel(II) Schiff base complexes, viz. Ni(salbn) and Ni(Me2-salpn), were employed as precursor in solid-state thermal decomposition. Structure, purity and morphology of these nanoparticles have been examined by Fourier transform infrared spectroscopy, X-ray powder diffraction, scanning electron microscopy and transmission electron microscopy (TEM). TEM analysis reveals that the synthesized nanoparticles have cubic particles with an average diameter of around 5–15?nm. This method is simple, less costly, and fast and safe for production of NiO nanoparticles in industrial applications.
