SYNTHESIS OF NANOCRYSTALLINE NICKEL OXIDE POWDERS VIA GLYCINE-NITRATE COMBUSTION
Abstract:
<p align="justify"> NiO is a candidate material for a variety of potential applications, for example, active optical filters, antiferromagnetic layers, coloring agents for enamel, pigments, catalysts, cathode materials for alkaline batteries and temperature sensors. Nanocrystalline nickel oxide powders have been synthesized by the combustion technique using glycine as a fuel and nitrate as an oxidizer. The precursor solution was heated to evaporate water, yielding a viscous liquid. It ignited and underwent self-sustaining combustion, producing an ash composed of the oxide product. The as-synthesized particles have been characterized by Xray diffraction (XRD), and scanning electron microscopy (SEM). Nanocrystalline nickel oxide was possible to be obtained from fuel-lean ratios. The smallest crystallite size was obtained under fuel-lean (0.09) formulation. The size of the NiO nanoparticles varied from 4 to 18 nm. </p>
