In this article, carbon nanotubes were grown on free standing multi-layer graphene sheet to form three dimensional carbon (3D-carbon) materials, and then used as support of Fe 2 O 3 nanoparticles. Ultrasmall Fe 2 O 3 nanoparticles were uniformly deposited on the surface of the 3D-carbon. Due to the synergistic effect of Fe 2 O 3 nanoparticles and 3D-carbon, the electrochemical properties are higher than that of bare Fe 2 O 3 material and multi-layer graphene sheet supported Fe 2 O 3 . Reversible capacity 528 mAh g- 1 is maintained at a high current density of 500 mA g −1 after 50 cycles. This composite shows a stable cycling and high rate performance.
