Synthesis of magnetic graphene-Fe3O4 nanocomposites by electrochemical exfoliation method

Authors

Abstract:

Superparamagnetic few-layer graphene nanocomposites (FLG- NCs) can be used for many technological applications, such as solar cells, batteries, touch panels and supercapacitors. In this work, we applied electrochemical exfoliation method as a simple, one step and economical technique to fabricate FLG- NCs. The fabricated Superparamagnetic FLG- NCs were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), field emission scanning electron microscope (FESEM), energy dispersive spectroscopy (EDS) and vibrating sample magnetometer (VSM). Analysis of XRD pattern shows the formation of graphene iron oxide nanocomposites due to the existence of magnetite (Fe3O4) and graphite picks. Hysteresis curve of the sample represents superparamagnetic effect with saturation magnetization, MS=57.3 emu. g-1. The results of XRD and VSM indicate that the size of ferromagnetic particles reduced to critical size to form into superparamagnetic. FLG- Fe3O4 with high saturation magnetization is very useful in hyperthermia, drug delivery, supercapacitors, removal dye, etc.

Few-layer graphene obtained by electrochemical exfoliation of graphite cathode

Few-layer graphene has been prepared by electrochemical intercalation of graphite cathode using Na/ dimethyl sulfoxide complexes as intercalation agent. By adding thionin acetate salt into the electrolyte, the exfoliated graphite is stabilized and further exfoliated into few-layer graphene. Raman and X-ray photoelectron spectra indicate that the graphene material has lower content of defects an...
