Tuning oxygen clusters on graphene oxide to synthesize graphene aerogels with crumpled nanosheets for effective removal of organic pollutants

Previously available synthesis of crumpled graphene is always based on external substrates or triggers, and it is still a daunting challenge to construct three-dimensional (3D) porous graphene aerogels with crumpled nanosheets without additional corrugation-inducers. Here, we report a novel and facile method to fabricate crumpled dispersive nanosheets in water directly by tuning oxygen clusters on graphene oxide itself through general...
