A kind of MnO2 nanobelt/nitrogen-doped graphene aerogel composite material for supercapacitor and its preparation method and application |
| abstract |
The invention provides a MnO 2 nanobelt/nitrogen-doped graphene aerogel composite material for supercapacitors and a preparation method and application thereof. The method of the invention prepares a nitrogen-doped graphene aerogel with a large specific surface area and a hierarchical pore structure through a hydrothermal reaction, then adsorbs KMnO 4 , and then adds MnSO 4 to reduce the nitrogen-doped graphene aerogel adsorbed on the nitrogen-doped graphene aerogel. KMnO 4 , resulting in MnO 2 nanoribbons with high surface unit cell exposure ratio. The strong chemical bonding between MnO2 nanoribbons and nitrogen-doped graphene aerogels not only improves the structural stability and cycling stability, but also facilitates the rapid electron transport and improves the electrochemical performance. The carbon skeleton-protected MnO2 nanoribbons/nitrogen-doped graphene aerogel composites exhibit excellent supercapacitor properties such as specific capacitance, specific energy, specific power, and cycling stability. |
