Iodine substituted graphene was synthesised in order to obtain a metal free catalyst for the oxygen reduction reaction (ORR). The doping with iodine was performed by electrophilic substitution of commercial graphene. The samples were characterised by wavelength dispersive X-ray fluorescence (WDXRF) spectroscopy, Scanning Electron Microscopy (SEM), and thermal gravimetric analysis. The electrochemical performances were investigated by cyclic voltammetry, there were evaluated and compared with a typical PEMFC configuration. In this paper, we present a facile synthesis protocol for preparation of iodine doped-graphene materials, whose evidenced properties could be inserted in subsequent development of ORR electrode modifications.
