| Outline of Final Research Achievements |
Photoreduction of graphene oxide (GO) has been known to be attractive for synthesizing the graphene-derivatives with high-throughput. We have reported the vacuum ultraviolet light irradiation processes for synthesizing the reduced graphene oxide (rGO) under high vacuum. In this study, we tried to synthesize the heteroatom-doped rGO through the chemical reaction between precursor and GO, followed by the VUV light irradiation. The VUV irradiation to nitrogen doped GO sheets results in the pyridinic N formation, and in the decrease of the sheet thickness. These results indicates that the wavelength can control the photochemical modification of GO.
