Abstract:
Graphene is a two-dimensional nano-material with the thickness of only one carbon atom, which is consisting of carbon atoms in the hexagonal honeycomb lattice formed by sp2 hybrid orbitals, exhibiting high specific surface area and excellent electrical, thermal, optical and mechanical properties, as well as exceptional hydrophobicity/superlipophilicity. Therefore, graphene is promising in the fields of adsorption and separation due to its unique structure and properties. The paper gives a comprehensive review to the recent studies about the fabrication of graphene-plus adsorption functional materials (grapheme-based sponge, graphene hydrogel/aerogel, graphene/carbon nanotubes), graphene-plus separation functional membrane materials (graphene porous membrane, graphene-plus polymer separation membrane, layer-by-layer graphene membrane), and graphene-plus continuous oil adsorption and separation functional materials. Moreover, the research progress and application prospect in oil/water separation process were analyzed and investigated.
Key words: graphene, graphene oxide, adsorption, saparation, functional material
