A Simple Electrochemical Fabrication and Characterization of Superparamagnetic Nanocomposite of Iron Oxide Nanoparticles Grown onto Amine-Functionalized Porous Graphene

In this research, Co-doped Fe3O4/NH2-graphene nanocomposite is produced by direct current electrodesotion technique from an aqueous electrolyte containing the iron/cobalt chloride/nitrate salts and amine-functionalized porous graphene. The applied electrochemical parameters were i=5 mA/cm2, Tbath=25oC and tdeposition= 15 min. The electrochemical growth of magnetic particles onto graphene layers and formation of Co-IONPs/f-PG composite were tuned through XRD, FT-IR, FE-SEM, VSM and EDAX analyses. The magnetite phase and particle morphology of the deposited iron oxide onto graphene layers was indicated by XRD pattern and FE-SEM images. The cobalt content of deposited iron oxide was clearly revealed in the EDAX data. The magnetic measurement by vibrating sample magnetometer (VSM) technique exhibited superparamagnetic nature with saturation magnetization and retentivity values of 47.65 emu g–1 and 2.26 emu g–1 for the electro-synthesized magnetic nanocomposite. In final, direct cathodic electrodeposited is proposed as simple procedure for production of iron oxides with various graphene-based materials.
