graphene oxide aerogel (RGO aerogel) is successfully synthesized
via simultaneous reduction and self-assembly of graphene oxide (GO)
sheets under γ-ray irradiation. As the resulting RGO aerogel
possesses an interconnected macroporous structure with strong hydrophobicity
and oleophilicity, it has great potential in oil–water separation.
Adsorption–distillation and adsorption–combustion are
both utilized to treat oil floating on water or oil sinking below
the water surface. More importantly, a simple device has been developed
to adsorb continuously and collect floating oil, and it has shown
great promise for practical application.
