| titleOfInvention | A method for preparing nitrogen-doped graphene aerogel with SiO2-NH2 as template and nitrogen dopant at the same time |
| abstract | The invention provides a method for preparing nitrogen-doped graphene aerogel by using SiO2 - NH2 as template and nitrogen dopant simultaneously. The graphene sheets were prevented from stacking and simultaneously acting as a dopant by using amino-functionalized silica ( SiO2 - NH2 ) as a template. The microstructure, porosity and chemical composition of graphene were analyzed by SEM, TEM, XRD patterns, Raman, XPS and BET, etc., and it was shown that the content of SiO 2 ‑NH 2 has a significant effect on the surface area and carbon activity of graphene flakes. significant impact. Benefiting from a large specific surface area of 481.8 m 2 g -1 and a high nitrogen doping content (4.4%), the fabricated 3D hierarchical porous graphene gel electrode exhibits excellent electrochemical performance, such as at a current density of 1 A g -1 It exhibits an ultra-high specific capacitance of 350F g -1 with good reversibility after 5000 cycles in aqueous and organic electrolytes with a cycle efficiency of 92.8%. In addition, N-doped graphene aerogels have high oil absorption and good recyclability. The steps are simple, the operation is convenient, and the practicability is strong. |
