Preparation of chloro-functionalized reduced graphene oxide by silver-catalyzed radical reaction

We report the development of a new synthesis method of chloro-functionalized reduced graphene oxide (rGOCl). The rGOCl was prepared by radical reaction, and treatment of carboxyl graphene oxide (GOCOOH) with N-chlorosuccinimide (NCS) at 90 °C for 10 h under an atmosphere of nitrogen, using silver nitrate as catalyst.
