A kind of nitrogen-doped graphene manganese oxide nanowire composite material and preparation method and application thereof |
| abstract |
The invention discloses a nitrogen-doped graphene manganese oxide nanowire composite material and a preparation method and application thereof. The preparation method of the invention adopts wet chemistry to grow manganese oxide on the surface of the graphene oxide sheet, enhances the bonding between the graphene and the manganese oxide, and reduces the high contact resistance caused by the mechanical mixing of the graphene and the manganese oxide; Urea is the nitrogen source, and the graphene oxide in the composite material is doped with nitrogen and the reduction of graphene oxide is realized. The hydrothermally modified manganese oxide can be transformed into nanorod-like or nanowire structures with higher specific surface area, which is beneficial to enhance the electrochemical active sites of the composites, while the in-situ growth of manganese oxide on the graphene surface reduces the graphene The contact resistance between manganese oxide and manganese oxide, and nitrogen doping of graphene further enhances the electrical conductivity and electrochemical activity of graphene. The preparation method of the invention has cheap and easy-to-obtain raw materials, and the adopted wet chemical method and hydrothermal method are simple in process and low in cost, and are suitable for large-scale production. |
