Green synthesis of NiFe2O4 nanoparticles using different fuels and their structural characterization

Abstract

Nickel ferrite nanoparticles have been prepared using clove and citric acid as fuels. Present work focuses the rapid, eco-friendly, inexpensive, green synthesis over regular chemical routes for the preparation of most applicable Nickel ferrite nanoparticles. Here we use Clove (Syzygium aromaticum) extract and citric acid as fuel for green and chemical route synthesis of nickel ferrite nanoparticles respectively. The synthesis of metal nanoparticles using clove extract is a modern alternative for their production. The combination of methods of soft chemistry and green chemistry is the ideal synthesis strategy. Their structural properties are characterized using X-ray diffraction (XRD) study. The XRD study revealed the cubic spinel structure of the Fd3m space group. Also found 24 nm and 26 nm average crystallite size of NiFe2O4-clove and NiFe2O4-C6H8O7 nanoparticles respectively. This comparative study helps to increase attention in various research areas leading to materials that are relatively reproducible and have excellent properties using environmentally friendly, non-toxic and bio-composite reagents.
