In this article, we demonstrate a general approach to grow Mo2C nanoparticles of 10-40 nm on a graphene (GR) support through a simple and environmentally friendly carburization process. The unique and special structural features of the Mo2C/GR hybrids including good structural robustness, small particle size and porous structure permit easy access for electrons and ions to the electrode/electrolyte, when the resulting materials are used as anode materials for lithium-ion batteries. Electrochemical tests indicate that the Mo2C/GR hybrids exhibit much better lithium storage properties than pure GR and bulk Mo2C electrodes. The enhanced electrochemical properties of the Mo2C/GR hybrids are mainly ascribed to the synergetic effects between Mo2C nanoparticles and the highly conductive GR support. The results clearly demonstrate that the Mo2C/GR hybrids have potential application as anode materials in high-performance energy storage devices.
