Spongy graphene (SG) shows highly efficient absorption of not only petroleum products and fats but also common toxic solvents such as toluene and chloroform, taking in up to 86 times its own weight. This is several to tens of times higher than that of conventional absorbers. Moreover, the SG can be regenerated more than ten times by heat treatment yielding the full release of adsorbates.
