Lysine-modified graphene oxide is synthesized and exploited as an adsorbent of emerging contaminants in drinking water.

We present an environmentally benign methodology for the covalent functionalization (arylation) of reduced graphene oxide (rGO) nanosheets with arylazo sulfones. A variety of tagged aryl units were conveniently accommodated at the rGO surface via visible‐light irradiation of suspensions of carbon nanostructured materials in aqueous media. Mild reaction conditions, absence of photosensitizers, functional group tolerance and high atomic fractions (XPS analysis) represent some of the salient features characterizing the present methodology. Control experiments for the mechanistic elucidation (Raman analysis) and chemical nanomanipulation of the tagged rGO surfaces are also reported.

Microwave (MW) accelerated synthesis combined to microfiltration (MF) on commercial hollow fiber modules enable fast and easy upscale of highly pure modified graphene oxide nanosheets. The MW-MF procedure is demonstrated...

Graphene oxide nanosheets have shown promising adsorption properties toward emerging organic contaminants in drinking water. Here, we report a family of graphene oxide nanosheets covalently modified with amino acids, and...
