▎ 摘　　要

NOVELTY - Preparing carbon nanotube/nitrogen-doped graphene/porous carbon composite gas gel comprises preparing carbon nanotubes, zeolitic imidazolate framework-8 (ZIF-8) metal-organic frameworks and graphene oxide-grafted polyaniline respectively, dispersing the carbon nanotubes and graphene oxide grafted polyaniline in deionized water, adding ZIF-8 metal organic framework, continuously and ultrasonically dispersing and stirring to obtain carbon nanotube/graphene oxide grafted polyaniline/ZIF-8 dispersion, pouring carbon nanotube/graphene oxide grafted polyaniline/ZIF-8 dispersion into mold, sequentially freezing the liquid nitrogen, freeze-drying to obtain carbon nanotube/graphene oxide grafted polyaniline/ZIF-8 gas gel, grafting the carbon nanotube/graphene oxide polyaniline/ZIF-8 gas gel, heating from 25℃ to 250-300℃ for 2-3 hours under nitrogen protection, then heating to 900-1000℃ for 10-15 hours to obtain the finished product. USE - The method is useful for preparing carbon nanotube/nitrogen-doped graphene/porous carbon composite gas gel used in adsorption and catalytic field. ADVANTAGE - The method: prevents the stack of the graphite; and improves the contact and the electrolyte solution, and specific capacitance of the gas gel material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a carbon nanotube/nitrogen-doped graphene/porous carbon composite gas gel prepared by the above-mentioned method.
