Abstract

In this report, we describe a simple two-step electrodeposition method to synthesis Mn2O3/electrochemically reduced graphene oxide (ErGO) nanocomposites on the surface of Ni foam (NF) and used as the electrode of supercapacitors (SCs). The scanning electron microscope (SEM), characterization had shown that three-dimensional (3D) Mn2O3 nanoflakes were uniformly loaded on the ErGO/NF. The electrochemical experiments show that the introduction of ErGO improve the electrochemical performance of Mn2O3 greatly due to the large surface area and high conductivity of ErGO, which provide enough place for Mn2O3 and decrease the resistance. In addition, the 3D network of Mn2O3 also own high surface area and porous structure. In one word, the synergistic effect of the ErGO and 3D network of Mn2O3 made the electrode possesses high specific capacitance of 114.3 F g-1 at a current density of 1 A g-1.
