Fabrication of Nickel - Copper Ferrite Nanocomposite Based on Graphene

Nickel-copper nanoferrites with different weight ratios were synthesized by combustion method. Graphene was prepared from microporous graphite powder using liquid phase exfoliation. The obtained graphene was analysed by Raman spectra. Then graphene was combined with nickel-copper nanoferrites to prepare nickel-copper nanocomposites based on graphene. The optical, structural and magnetic properties of nanocomposites were investigated by analyses of XRD, FTIR, SEM, UV-VIS and VSM. The XRD diffraction patterns revealed the formation of nanoparticles with cubic spinel structure, and the formation of the ferrite phase can be confirmed according to the FTIR results of the vibrational mode of the Fe ions located at the quadrilateral position ofthe oxygenoxygen lattice. The SEM microscopic images showed more porosities in nanocomposites that indicate these structures have a large surface area that is useful in trapping viruses and bacterias. Also this study could be used in photothermal therapies research.
