CHAPTER 11: 3D Graphene-based Macrostructures as Superabsorbents for Oils and Organic Solvents

With frequent occurrence of oil spill incidents and accidental leakage of organic solvents, the development of highly efficient and environmentally friendly absorbents with both hydrophobic and oleophilic properties have become a top priority. This chapter collates the current state-of-the-art on the development and application of ultralight and mechanically resilient 3D GBMs for the selective absorption of a broad variety of oils and organic solvents, with an emphasis on underlying mechanisms. Furthermore, it highlights the fundamental knowledge gaps in the domain and lays out novel strategic research guidelines, all of which would promote further progress in this rapidly evolving cross-disciplinary field of current global interest.
