Amine-functionalized graphene aerogel was prepared through gelation and in situ reduction of GO by using polyethylenimine, and subsequent freeze-drying of the resultant graphene hydrogel. Having a large specific surface area, continuous pore structures, and active chemical adsorbing sites, the graphene aerogel exhibited better properties in adsorbing formaldehyde.
