Facile synthesis of Fe3O4 nanoparticles decorated on 3D graphene aerogels as broad-spectrum sorbents for water treatment

Water contaminants, such as oils, dyes, arsenite ions and organic solvents can be efficiently sorbed by two kinds of 3D magnetite-graphene aerogels (M-RGOs) with the size of Fe3O4 NPs of about 10 nm.
