The Fe3O4/MnO2/RGOs sandwich-like nano-superstructures were fabricated. 3D hierarchical MnO2 shell was assembled by two-dimensional 2D nanoplates. They show better electrochemical performance comparing to MnO2 and Fe3O4/MnO2. The electrochemical properties are highly affected by the connection effectiveness. They have greater potency including water purification, microwave adsorption, etc.
