We prepared 3 4 Received 4 August 2014 Fe O /graphene nanocomposites with different microwave powers – 200, 600, and 1000 W. The structure 3 4 Received in revised form 22 December 2014 and morphology of the Fe O /graphene nanocomposites were characterized by X-ray diffraction (XRD), 3 4 Accepted 18 January 2015 scanning electron microscopy (SEM) and high-resolution transmission electron microscopy (TEM).
