▎ 摘  要

NOVELTY - Nitrogen-doped graphene airgel preparation involves taking and mixing 1-10 pts. wt. graphene oxide solution, 0.5-12 pts. wt. nitrogen source and 1-30 pts. wt. plant extract with stirring ultrasonically to obtain mixed liquor, and then transferring the mixed liquid into high pressure reactor at 80-200 degrees C for 12-20 hours to obtain hydrogel. The obtained hydrogel is pre-cooled at 0 to -20 degrees C for 1-12 hours, and then naturally dried to obtain the nitrogen-doped graphene airgel. USE - Method for preparing nitrogen-doped graphene airgel (claimed) used for preparing different micro-switches, micro-motion sensors, super-capacitors, lithium batteries, solar cells, refractory materials, catalytic materials, adsorption materials, oil absorption materials or other fields. ADVANTAGE - The method prepares the nitrogen-doped graphene airgel in a simple manner with high nitrogen doping amount. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical representation depicting volume retention rate curves of the prepared nitrogen-doped graphene airgel.
