摘要
We fabricated KOH-activated reduced graphene oxide (rGO)/Fe2O3 composites using a facile two-step synthesis by homogeneous precipitation and subsequent reduction of the GO. The total specific capacity of Fe2O3/KOH-activated rGO was higher than the sum of KOH-activated rGO and nanoparticle Fe2O3. It indicated a synergy effect of rGO, and Fe2O3 on the improvement of electrochemical performance. The structure and morphology of the composites were characterized by Fourier transform infrared spectrometer (FTIR), scanning electron microscopy (SEM). Electrochemical properties were characterized by cyclic voltammetry (CV) and charge-discharge (CD) in 6M KOH electrolyte.
