Electrochemical energy storage devices,which typically include lithium-ion batteries and supercapacitors [1-9],have drawn worldwide interests since the realization of the energy crisis.Among all the materials applicable for Li-ion batteries,the composites of the high performance carbon@transition metal oxides or nitrides have always been regarded as the more promising candidates due to their higher theoretical capacity,improved rate capability and enhanced cyclability during operations [2-9].

石墨烯是一种具有单原子厚度的二维片状结构的新材料.其优越的导电性和电子传输性能在储能,锂离子电池,超级电容器和电催化等多个领域显示出了广阔的应用前景[1].然而,由石墨烯氧化物还原得到的石墨烯会发生聚集或叠加,因此石墨烯的表面积会降低,电子传输能力也会大幅度降低,其电催化性能随之受到很大影响.
