Two types of structure models, c.f. g-C₃N₄ and melon, are proposed to graphitic Carbon Nitride materials. We showed that the structure models are distinguished by the measurement of NEXAFS spectra. In this study, to investigate the effect of oxidation to these materials, we have compared the NEXAFS spectra calculated by first principles calculations of these materials with and without oxidation.
