3-D graphene–carbon nanotube-nickel nano-architectures for supercapacitors |
| 초록 |
We report a simple and facile technique to transform naphthenic acid treated 2-D graphene oxide to 3-D, mesoporous graphene-carbon nanotube(G-CNT) hierarchical nano-architectures using nickel as the catalyst and microwave as the energy source. The as-prepared G-Ni-CNT structure is highly porous and exhibit good conductivity. When applied as electrodes in super-capacitor, our G-Ni-CNT shows high specific capacitance of 894 F g-1 at a current density of 1 A g-1 in 6 M KOH electrolyte solution, with good rate capability and cycling stability. Furthermore, the utility of our newly (This work was supported by the National Research Foundation of Korea (NRF) grant funded by the Korea government (MSIP) through GCRC-SOP (No. 2011-0030013)) |
