Preparation and characterization of nickel oxide nanoparticles via solid state thermal decomposition of dinuclear nickel(II) Schiff base complex [Ni2(Brsal-1,3-ph)2] as a new precursor

Abstract

The synthesis and characterization of nickel oxide nanoparticles via solid state thermal decomposition of a dinuclear nickel(II) complex, [Ni2(Brsal-1,3-ph)2] as a new precursor is reported. [Ni2(Brsal-1,3-ph)2] complex is characterized by elemental analyses and Fourier transform infrared (FT-IR) spectroscopy. Thermogravimetric analysis reveals its thermal stability and decomposition pattern. Solid state thermal decomposition of the complex at 450 °C for 3 h produces nickel oxide nanoparticles which are characterized by FT-IR spectroscopy, X-ray powder diffraction, scanning electron microscopy (SEM), and transmission electron microscopy (TEM). SEM and TEM images demonstrate the square shape of the NiO nanoparticles of between 10 and 15 nm.
