Facile fabrication of stable monolayer and few-layer graphene nanosheets as superior sorbents for persistent aromatic pollutant management in water

Abstract

A facile method was employed to prepare stable monolayer and few-layer graphene (ASG) nanosheets by loading on nanosilica substrates. The adsorption capability of ASG was enhanced by a factor of up to 10² for phenanthrene compared with pristine graphene, which was higher than that in previous reports for nanomaterials. Interaction mechanisms of monolayer graphene with organic solutes were discussed.
