In this paper, we propose a facile one-step strategy to prepare Fe3O4@amorphous carbon/reduced graphite oxide nanocomposites (FCRGs) under hydrothermal conditions. A transmission electron microscopy image has shown that the as-formed Fe3O4 nanoparticles coated with a layer of amorphous carbon are wrapped by reduced graphite oxide (r-GO) sheets. The diameter of Fe3O4 nanoparticles is less than 50 nm. N-2 adsorption/desorption isotherms indicate that the specific surface area of FCRG is 31.6 m(2)/g with porous structure. FCRG exhibits improved cycling stability and rate performances as a potential anode material for high-performance lithium ion batteries. (C) 2014 Elsevier Ltd. All rights reserved.
