Fabrication of graphene/carbon nanotube paper decorated with nanoneedle MnO2 on the outermost graphene sheets for supercapacitors |
| 초록 |
Herein, 3D nanohybrid architectures consisting of nanoneedle MnO2, carbon nanotubes (CNT) and graphene sheets are fabricated. Nanostructured ternary hybrid papers in which MnO2 nanoneedles formed on the outermost graphene layer and CNT intercalated between graphene layers by using the amide bonds are fabricated using the direct paper dipping method. The intercalated CNT can separate the graphene layers and thus create the effective surface area which is associated with large electrochemically active sites as well as form the electronic conductive channel inside the nanohybrid paper. These nanostructured ternary hybrid papers exhibit enhanced specific capacitances compared with graphene-only or graphene/CNT papers. The proposed nanohybrid architectures are expected to lay the foundation for the design and fabrication of high-performance electrodes. |
