Abstract

original image

Spongy graphene (SG), a nanoporous material with a high surface area, is used as a versatile and recyclable sorber. On page 4421, Litao Sun, Rodney S. Ruoff, and co-workers report that SG shows highly efficient absorption of petroleum products, fats, and toxic solvents and can be regenerated by heat treatment, yielding almost full release of the adsorbates. SG shows a widespread potential for applications in industry and environmental protection.
