摘　　要：Micro-size oil adsorbents are effective for the rapid remediation of special oil spills.Here,N-doped reduced graphene oxide(RGO)microspheres(ca.150µm in diameter)with a local radially aligned and porous structure are fabricated by combining electrospray-freeze-drying with thermal treatment for rapid separation of oil-water.Owing to its hydrophobic/oleophilic properties and oriented structure,the N-doped RGO microspheres achieve high capacities and fast adsorption rates for a variety of oils and organic solvents.Furthermore,excellent oil-water separation performance on floating oil/oil-water emulsions and stable cyclic adsorption capacities are obtained for the local radially aligned and porous microsphere.Therefore,N-doped RGO microspheres with the unique porous structure have the potential for the remediation of oily sewage and oil spills.
