Abstract:
Recently, upsurge attention is made on manufacturing of magnetic nanocomposites based ongraphene [1]. Toward this, in this paper, we investigate for the first time, the effect of cathodematerials on the morphology and graphene quality of product graphene cobalt nanocomposite.The nanocomposite is synthesized by electrodeposition method with different cathode materialssuch as Pt, Ni, St, Cu and Fe. Synthesized samples are characterized by X-ray diffraction (XRD),scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), Fouriertransform infrared spectroscopy (FTIR) and vibration sample magnetometer (VSM). Accordingto XRD results, in synthesized sample with Ni and Pt cathodes two wide peaks of grapheneappears in addition to cobalt s peacks. Images of SEM and information taken from EDX showextended graphene flakes. Magnetization of all samples are in the same ranges of 111~129emu/g. Magnetic nanocomposites based on graphene might have potential applications as freestandingelectrode materials for functional electronic elements such as supercapacitors andsensors [2, 3].
