Scalable production of wrinkled and few-layered graphene sheets and their use for oil and organic solvent absorption
journal contribution

Graphene sheets were produced by first ball milling of graphite with ammonium chloride followed by thermal annealing at 800 °C in nitrogen gas. The few layered graphene sheets show highly efficient selectivity and capacity for the absorption of petroleum products as well as organic solvents such as ethanol, cyclohexane and chloroform (up to 82, 42 and 98 times of their own weight, respectively). The saturated few-layered graphene sheets can be cleaned for reuse by simply burning in air. The low-cost strategy for mass production and easy recycling routes demonstrate the great potential of few-layered graphene sheets for oil removal.
