Facile and cost-effective synthesis of flower-like RGO/Fe3O4 nanocomposites with ultra-long cycling stability for supercapacitors
The RGO/Fe3O4 nanocomposites were synthesized by an easy and cost-effective graphenothermal process during which GO and Fe2O3 were reduced to RGO and Fe3O4, thus forming the RGO/Fe3O4 nanocomposite. This material...
