A facile synthesis of porous graphene for efficient water and wastewater treatment.

摘要: The use of two-dimensional graphene-based materials in water treatment has recently gained significant attention due to their unique electronic and thermal mobility, high surface area, mechanical strength, excellent corrosion resistance tunable chemistry. However, the relatively expensive, poor hydrophobicity, low adsorption capacity recyclability, complex post-treatment most pristine graphene frameworks limit practical application. Here, we report a facile scalable method produce highly porous from reduced oxide via without addition any catalyst or template. Comparing conventional counterparts, as-prepared nanosheets showed evident improvement capacity, making them ideal candidate for treatment. Superhydrophobic superoleophilic prepared this work been demonstrated as effective absorbents broad range ions, oils organic solvents, exhibiting selectivity, good absorption capacities > 90%. synthesis reported paper is easy implement, cost scalable. These attributes could contribute towards efficient cost-effective purification pollution reduction.
