Sol-gel combustion and characterization studies of nickel oxide nanoparticles using microwave synthesis

Abstract

Semiconductor NiO nanoparticles were successfully synthesized by a simple sol-gel combustion method using urea as the fuel. The prepared NiO nanoparticles were characterized by powder XRD pattern, SEM, TEM, EDX analysis and VSM analysis. Powder XRD results were confirmed the pure form of cubic NiO phase. Surface morphology of the NiO nanoparticles was analyzed by SEM and TEM analysis, and confirmed the particle like nano-crystal morphology. of the samples were investigated by room temperature VSM and their magnetic - hysteresis (M-H) loop confirmed the super paramagnetic behavior of the NiO nanoparticles.
