A Method for Synthesis of Nitrogen-Doped Graphene with High Specific Surface Area

Abstract

A method for synthesis of nitrogen-doped graphene (N-graphene) with high specific surface area has been developed. In this method, magnesium oxide is used as a template where a carbon layer modified with nitrogen atoms is deposited. Nitrogen–carbon–mineral composites (N–C/MgO) containing from 5 to 27 wt % of nitrogen-doped carbon have been synthesized. After dissolving magnesium oxide, N-graphene with a specific surface area of 1300–1400 m2 g–1 has been synthesized for the first time. The synthesis of N-graphene has been characterized by electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy.
