摘要：
Hollow Fe2O3/graphene nanocomposites were synthesized by a hydrothermal method, and they were characterized by XRD and SEM. A plausible formation mechanism for the nanocomposites could be based on the catalytic oxidation of carboxyl groups of graphite oxide(GO) in the presence of Fe3+ ions to form graphene nanosheets(GNS), and the released CO2 provided templates for the formation of hollow Fe2O3, and then hollow Fe2O3/graphene nanocomposites were formed in-situ. The obtained nanocomposites show excellent Li storage performances. After 50 cycles, a capacity of 520 mA . h/g(437 mA . h/g) was kept at a high current density of 200 mA/g(400 mA/g).
