One-Pot Hydrothermal Preparation of Fe3O4 Decorated Graphene for Microwave Absorption

Fe3O4 decorated graphene was synthesized for electromagnetic wave absorption via a facile one-pot hydrothermal approach. The structure and morphology of the as-prepared nanomaterials were systematically investigated. The graphene oxide (GO) was reduced a...
