Effect of cathode materials on morphology and quality of electrodeposited magnetic graphene nanocomposite

Recently, upsurge attention is made on manufacturing of magnetic nanocomposites based on graphene [1]. Toward this, in this paper, we investigate for the first time, the effect of cathode materials on the morphology and graphene quality of product graphene cobalt nanocomposite. The nanocomposite is synthesized by electrodeposition method with different cathode materials such 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), Fourier transform infrared spectroscopy (FTIR) and vibration sample magnetometer (VSM). According to XRD results, in synthesized sample with Ni and Pt cathodes two wide peaks of graphene appears in addition to cobalt s peacks. Images of SEM and information taken from EDX show extended graphene flakes. Magnetization of all samples are in the same ranges of 111~129 emu/g. Magnetic nanocomposites based on graphene might have potential applications as freestanding electrode materials for functional electronic elements such as supercapacitors and sensors [2, 3].
