It is well-known that chemical functionalization of graphene has the great significance. 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℃ for 10 h under an atmosphere of nitrogen, using silver nitrate as catalyst. The morphologies and structures of the prepared materials were investigated by field-emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy and the thermal gravimetric. Results indicated that the rGOCl can be readily obtained from graphene oxide (GO) in three steps.
