The alpha-MnO2 nanofibers are synthesized on graphene surface by using MnSO4 and ammonium persulfate as an oxidant. The results show formation of aggregated bundles (size about 15-30 nm) of 1D alpha-MnO2 nanofibers on the graphene surface. In supercapacitor, the unique nanofibrous morphology of MnO2 on 3D GF electrode exhibits higher specific capacitance (670 F g(-1)) than on the conventional current collector (CC) electrode (440 F g(-1)).
