A new paradigm of ultrathin 2D nanomaterial adsorbents in aqueous media: graphene and GO, MoS2, MXenes, and 2D MOFs

Due to the high surface area, atomic-level thickness, and abundant exposed active sites, 2D nanomaterials are regarded potential high-performance adsorbents. We review four representative nanomaterials, graphene, MoS₂, MXenes, and MOFs, for this application.
