A facile hydrothermal method was developed for the preparation of Fe2O3@C nanocomposites using FeCl3 ? 6H2O as iron source and glucose as carbon source under alkaline condition. The morphology and structure of the as-prepared product were identified by transmission electron microscopy (TEM), high res-olution transmission electron microscopy (HRTEM), field-emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), Raman spectroscopy, Fourier Transform infrared spectroscopy (FTIR), and thermo-gravimetric analysis (TGA). The as-prepare α-Fe2O3@C nanocomposites were employed for supercapacitor electrode material. The synergistic combination of carbon electrical double-layer capacitance and α-Fe2O3 pseudo-capacitance established such nanocomposites as versatile platform for high performance superca-pacitors. The synthesis method developed here is expected to obtain other metal oxide/carbon composite.
