通过在石墨烯表面直接生长FeOOH纳米棒，然后通过电化学转化制备Fe 3 O 4，在石墨烯上制备了二维片状氧化铁，作为超级电容器的高能阳极材料。在1 mol L-1 LiOH溶液中，Fe3O4@RGO纳米复合材料表现出优异的上级电容（326 F g（-1））、高能量密度（85 Wh kg（-1））、大功率和良好的循环性能。
2D sandwich-like sheets of iron oxide grown on graphene as high energy anode material for supercapacitors are prepared from the direct growth of FeOOH nanorods on the surface of graphene and the subsequent electrochemical transformation of FeOOH to Fe3O4. The Fe3O4@RGO nanocomposites exhibit superior capacitance (326 F g(-1)), high energy density (85 Wh kg(-1)), large power, and good cycling performance in 1 mol L-1 LiOH solution.
