Hydrophobic sorbents play a key role in the remediation processes of oil spills/leakages occurring globally. In present work, reduced graphene oxide modified porous diatomite ceramics with hierarchical pore structures and excellent mechanical strength were facilely fabricated using diatomite powder and graphene oxide as starting materials. The microstructures and absorption properties of reduced graphene oxide modified porous diatomite ceramics were investigated, and the results indicated that reduced graphene oxide entered into the pores of diatomite ceramics, and formed a membrane coating on the wall of the pores, which made the diatomite ceramics a highly efficient absorption for organic solvents, and the capability separating the organic counterpart from the oil/water mixture.

疏水性吸附剂在全球范围内发生的漏油/漏油的修复过程中起着关键作用。在目前的工作中，以硅藻土粉末和氧化石墨烯为起始原料，容易地制备了具有分级孔隙结构和优异机械强度的还原型氧化石墨烯改性多孔硅藻土陶瓷。对还原型氧化石墨烯改性多孔硅藻土陶瓷的微观结构和吸收性能进行了研究，结果表明，还原型氧化石墨烯进入硅藻土陶瓷的孔中，并在孔壁上形成了膜被膜，使硅藻土陶瓷成为一种硅藻土陶瓷。对有机溶剂的高效吸收，以及将有机对应物与油/水混合物分离的能力。
