摘要：

A hybrid material composed of nitrogen-doped graphene anchored with Fe2O3 was readily obtained by a facile and one-step hydrothermal method followed by assisting with microwave under mild conditions. Scanning electron microscopy and transmission electron microscopy images show that Fe2O3 with average size of 30-50 nm are homogeneously distributed and anchored on the surface of nitrogen-doped graphene sheets. The N-doped graphene/Fe2O3 hybrid electrodes exhibit excellent electrochemical performance with the charge/discharge capacity maintain stable at around 844.3 mAhg(-1) and 937.7 mAhg(-1) after the 40 th cycle. The enhanced lithium-storage performance is ascribed to the rational design of the hybrid and has a great potential as anode material for lithium ion batteries.
