Graphene and carbon-based nanomaterials as highly efficient adsorbents for oils and organic solvents

This paper provides a comprehensive review of recent progress in the synthesis and performance of graphene and carbon-based nanomaterials as efficient adsorbents for oils and organic solvents. Several advantages of these adsorbents are emphasized, including adjustable three-dimensional networks, high surface area, high chemical/thermal stability, high flexibility and elasticity, and extremely high surface hydrophobicity/oleophilicity. Technical challenges are discussed, and future research directions are proposed.
