Metal-organic frameworks (MOFs) and graphene aerogels (GAs) are both considered as good candidates for high-performance supercapacitors. In this work, a growth-oriented Fe-based MOF synergized with GA composite for supercapacitor is prepared. MIL-88-Fe is in situ grown at (002) lattice plane on the surface of graphene via a one-step solvothermal method. Long periodic hexagonal structure and electrophilicity of MOF provide strong p-pi interaction with graphene sheets. By utilizing the abundant interspace of GA, the existence of MOF could affect the electric double-layer characteristics of composites. The MOF/GA composites have the advantages of high capacitive volume, fast charge/discharge rate, and reliable cycling stability. The specific capacitance is as high as 353 F g(-1) at the scan rate of 20 A g(-1), and the retention ratio is 74.4% after 10 000 cycles.
