Facile preparation of NiFe2O4/NaCl nanocomposites by wet chemical co-precipitation

Abstract

In this work, we utilized various iron salts {Fe(NO3)3, FeSO4 and FeCl3} at the presence of aqueous solutions of NiCl2 and NaOH, respectively, to prepare NiFe2O4/NaCl nanocomposites using wet chemical co-precipitation. The dark-brown products were afterwards calcined for 3 h at 600 °C. All products were characterized using Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) and transmission electron microscopy (TEM). XRD results confirmed formation of the NiFe2O4/NaCl nanocomposites. The TEM results revealed that the particles are relatively similar in cube-like shape; however, the size was distinct.
