Water decontamination and oil/water separation are principal motives in the surge to develop novel means for sustainability. In this prospect, supplying clean water for the ecosystems is as important as the recovery of the oil spills since the supplies are scarce. Inspired to design an engineering material which not only serves this purpose, but can also be altered for other applications to preserve natural resources, a facile template-free process is suggested to fabricate a superporous, superhydrophobic ultra-thin graphite sponge. Moreover, the process is designed to be inexpensive and scalable. The fabricated sponge can be used to clean up different types of oil, organic solvents, toxic and corrosive contaminants. This versatile microstructure can retain its functionality even when pulverized. The sponge is applicable for targeted sorption and collection due to its ferromagnetic properties. We hope that such a cost-effective process can be embraced and implemented widely.
水净化和油水分离是开发可持续新方法热潮中的主要动机。在这种情况下，为生态系统提供清洁水与溢油回收同样重要，因为水资源稀缺。受启发设计一种工程材料，它不仅能实现这一目的，还可针对其他应用进行改进以保护自然资源，本文提出一种简便的无模板工艺来制备超多孔、超疏水超薄石墨海绵。此外，该工艺设计得成本低廉且可扩展。所制备的海绵可用于清理不同类型的油、有机溶剂、有毒和腐蚀性污染物。这种多功能微观结构即使被粉碎也能保持其功能。由于具有铁磁特性，该海绵适用于靶向吸附和收集。我们希望这样一种经济高效的工艺能够得到广泛采用和实施。
