Fund Project:

The composite electrode material of ferroferric oxide/nitrogen doping reduction graphene (Fe₃O₄/N-rGO) was successfully prepared by the hydrothermal method. Its structure and morphology were characterized using XRD, XPS, FESEM and TEM, respectively. The electrochemical performance of prepared material was studied by cyclic voltammetry and ac impedance and constant current charge and discharge technology. The results showed that the Fe₃O₄/N-rGO has higher specific capacitance and better cycle stability. Its specific capacitance is 291.7F/g under the current density of 0.5A/g, which is higher than those of pure ferroferric oxide and pure graphene. It is clear that the addition of smaller particle size of Fe₃O₄ reduces the agglomeration of graphene and improves the specific capacitance of composites greatly.
