A facile one‐step hydrothermal method is developed to synthesis Fe 3 O 4 @carbon foam hybrid nanostructure, in which the Fe 3 O 4 microspheres organized with nanoparticles are supported by the 3D porous carbon foam. The morphology of Fe 3 O 4 and composite structure all effective enhance the specific surface area and practicability. Cyclic voltammetry and galvanostatic charge/discharge were tested to characterization the electrochemical performance in a three electrode cell. The as‐synthesized composite exhibits remarkable pseudocapacitive activities and specific capacitance, rate performance and cycling stability were all be promoted. The results reveal that carbon foam as the economical carbonaceous material could be the next reliable carbonaceous host.
