Large-Scale Growth of Nitrogen-Doped via Solvothermal Synthesis
Abstract:
Theoretical studies predicted that doping graphene with nitrogen can tailor its electronic properties and chemical reactivity. We develop here a novel method for synthesis N-doped graphene via solvothermal synthesis process with urea as both reductant and nitrogen sources. The resulting N-doped graphene were characterized by various methods (UV-vis spectra, SEM and XPS). XPS analysis shows a predominant graphitic C 1s peak at ca. 285 eV, an O 1s peak at ca. 532 eV and N 1s peak at ca. 410 eV. Moreover, the atomic ratio of N/C is 5.0% for N-doped graphene, demonstrating nitrogen species have been successfully incorporated into N-doped graphene.
