X-ray diffraction and infrared characterization of NiFe2O4 nanoparticles (NFNPs) prepared using dextrose assisted sol-gel auto-combustion technique

In the current work, we comprehensively focused upon the synthesis of NiFe2O4 nanoparticles (NFNPs) via the sol-gel auto-combustion method. Particularly in the present investigation, we deployed dextrose (C6H12O6) as an organic compound that works as a fuel in the sol-gel synthesis of NFNPs. The as-prepared samples of NFNPs were characterized for structural properties through XRD. The crystallite size (t), the lattice constant (a), unit cell volume (V), and X-ray density dX of NFNPs was determined using XRD data. Crystallite size was obtained through Debye-Scherrer’s formula indicates the nanocrystalline nature of the prepared NFNPs sample. The infrared spectroscopy (IR) was carried out for investigating the presence of phases and the function group analysis in the NFNPs. The IR has confirmed the formation of ferrite phase in dextrose assisted sol-gel synthesized NFNPs as we report the intrinsic vibrations belongs to the tetrahedral and octahedral sites.
