FUNCTIONALIZATION OF GRAPHENE OXIDE BY NITROGEN

Abstract

In this paper, we used a straightforward method for the functionalization of graphene oxide with nitrogen. Functionalization with nitrogen makes it possible to significantly expand the possibilities of using graphene oxide in various fields of science and technology. The original graphene oxide sample and the glow discharge graphene oxide sample were deposited on the Si/SiO₂ surface with a layer thickness of more than 10 nm. During the study, the structure and surface chemistry of graphene oxide samples before and after treatment were characterized using X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, and scanning electron microscopy. Functionalization with nitrogen via glow discharge resulted in an increase in nitrogen and a decrease in oxygen levels.
