Robust Superhydrophobic/Superoleophilic Wrinkled Microspherical MOF@rGO Composites for Efficient Oil‐Water Separation

Graphene/MOF‐based composite materials in three‐dimensional (3D) architectures are promising for treatment of oil‐containing wastewater by absorption, given by their intrinsic properties of graphene and metal‐organic frameworks (MOFs) like high porosity, ultralow density and facilely tailored superwettability. Herein, novel wrinkled 3D microspherical MOF@rGO composites with both superhydrophobic and superoleophilic properties have been developed by embedding MOF nanoparticles between graphene oxide (GO) nanosheets followed by a high‐temperature reduction self‐assembly. The microspherical composites feature a unique micro‐nano‐hierarchy consisting of crumpled reduced GO (rGO) nanosheets intercalated with well‐dispersed MOF nanoparticles. Combined with the superwettability and abundant meso‐/micro‐porosity, the peculiar architectures of wrinkled ZIF‐8@rGO microspheres show very fast absorption rates and high sorption selectivity for organic solvents and oils from water. The ZIF‐8@rGO@Sponge composites are successfully utilized for efficient and long‐term stable oil‐water separation.
