Abstract
Nickel ferrite NiFe 2 O 4 nanoparticles were synthesized through sol-gel auto combustion method using dextrose as a fuel. The prepared nanoparticles were investigated for their structural, optical and magnetic characterization. X-ray diffraction (XRD) revealed the development of single-phase cubic spinel with crystallite size of 14 nm. The optical study showed that the compound has an optical band gap 2.26 eV. The magnetic properties were investigated through M-H hysteresis curve. The photocatalytic activity of nickel ferrite was studied based on the degradation of methylene blue (MB) as a model compound, where the results showed that prepared nanoparticles possess a good photocatalytic activity.
