Hengchang Bi, Xiao Xie, Kuibo Yin, Yilong Zhou, Shu Wan, Longbing He, Feng Xu, Florian Banhart, Litao Sun and Rodney S. Ruoff Graphene: Spongy Graphene as a Highly Efficient and Recyclable Sorbent for Oils and Organic Solvents (Adv. Funct. Mater. 21/2012) Advanced Functional Materials 22
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.
