Graphene-based aerogels with a three-dimensional interconnected network were fabricated via the hydrothermal self-assembly and thermal-annealing process. The aerogels were characterized by means of scanning electron microscopy and atomic absorption spectroscopy. The graphene-based aerogels showed highly porous structure and adsorption capacity for heavy metal ions. Thus, they would be the promising materials for removal of heavy metal ions from water.
