Abstract:Graphene nanosheets (GNS) anchored on Mn3O4nanoparticles have been successfully synthesized through in situ thermal decomposition of Mn (NO3)2without the use of any templates or surfactants. Mn3O4particles were coordinately distributed on the GNS surface. This was achieved by forming 3D nanostructures to avoid detrimental graphene layer stacking, and was characterized using a scanning electron microscope. The Mn3O4/GNS nanocomposite delivers an initial capacity of 1450 mAh g-1at a current density of 100 mA g-1. It also maintains a high reversible capacity of 930 mAh g-1even after 60 charge-discharge cycles without showing any apparent decay. © Published under licence by IOP Publishing Ltd.
