lignin biomass with hydrophobic and porous skeletons. The lignin-modified graphene
aerogel (LGA) show highly efficient absorption of not only petroleum oils, but also toxic
solvents such as toluene, chloroform and carbon tetrachloride (up to 350 times of its own
weight), which is superior to that of graphene aerogel (GA) and among the highest in
previous reported absorbents. Even after several compressive and release cycles, their …
