| titleOfInvention | Fluorine and nitrogen co-doped three-dimensional graphene material and one-step carbonization preparation method thereof |
| abstract | The invention discloses a fluorine and nitrogen co-doped three-dimensional graphene material, which is prepared by taking polytetrafluoroethylene and melamine as precursors, mixing and grinding the precursors uniformly, and then preparing the fluorine and nitrogen co-doped three-dimensional graphene material by a one-step carbonization method, wherein fluorine and nitrogen elements of the obtained three-dimensional graphene are distributed uniformly; the specific surface area is 1200-1400 m 2 g ‑1 Total pore volume of 2.5-2.9 cm 3 g ‑1 (ii) a The specific surface area of the material can be greatly regulated and controlled to be 50-1600 m by changing the carbonization temperature 2 g ‑1 The total pore volume is regulated and controlled to be 0.2-3.2 cm 3 g ‑1 In the meantime. The one-step carbonization preparation method comprises the following steps: 1, mixing raw materials; 2, one-step carbonization. The three-dimensional graphene in the material is uniform in grid, uniform in fluorine and nitrogen element distribution, good in repeatability, moderate in carbonization temperature, simple in process and easy to operate, and is synthesized by one-step carbonization. The material has wide application prospect in the field of super capacitors and in the direction of carbon functional materials. |
