Surface chemistry of graphene oxide (GO) plays an important role in possible applications of the material. Beside traditional approaches, like thermal treatment, ion beam irradiation has been recognized as a tool for modifying not only the surface chemistry, but also the structural properties of GO. In this study, the GO paper was irradiated with 15 keV proton beam with fluencies from 5×1016 to 2×1017 ions/cm2 . Surface chemistry of GO was monitored with Fourier-transform infrared spectroscopy (ATR-FTIR) and X-ray photoelectron spectroscopy (XPS) while structural changes were investigated with Raman spectroscopy. XPS and ATR-FTIR methods showed partial reduction of GO, with preferential desorption of basal plane alkoxy and epoxy oxygen groups. In terms of structural changes, intensity ratio of D and G peaks decreased linearly with the increase of C/O ratio i.e. increase of fluence. The reduction of GO with hydrogen atom was also investigated dynamically by semi-empirical calculations. ...The calculations for the epoxy group have identified energy ranges at which reduction is a consequence of physical (>20 eV) or chemical (<1.5 eV) processes. The results are showing a potential of ion beam irradiation for controllable modification of structural and surface properties which can be used for tuning of the charge storage properties of graphene oxide.
