چکیده
Herein, we report the structural, morphological, and chemical properties of the electrochemically   grown Co2+-doped magnetite (Co-Fe3O4) nanoparticles onto functionalized graphene oxide layers (Co2+-doped iron oxide@f-GO composite). The deposition process is done at the galvanostatic mode in the two-electrode system by applying the constant current density of 5 mA cm-2. The fabricated Co2+-doped iron oxide@f-GO composite is characterized via Scanning Electron Microscopy, energy dispersive X-ray analysis, Fourier Transform Infrared Spectroscopy (FTIR), Transmission Electron Microscopy (TEM), and X-Ray diffraction analysis. TEM observation revealed that Co-Fe3O4 has fine particle morphology with size of 5-10 nm. The FTIR data proved the graphene-based chemical nature of the fabricated composite. The superparamagnetic nature of the prepared composite is proved by vibrating sample magnetometer tests, which verified that the prepared metal-cation doped Fe3O4 nanoparticles grown onto functionalized GO layers could be an interesting candidate for further manipulations for biomedical aims such as drug delivery, magnetic resonance imaging, and hyperthermia.
