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.

一种高比表面积的掺氮石墨烯的合成方法

摘要

已经开发了一种具有高比表面积的氮掺杂石墨烯（N-石墨烯）的合成方法。在该方法中，氧化镁被用作模板，其中沉积有被氮原子改性的碳层。合成了含有5至27 wt％的氮掺杂碳的氮碳矿物复合物（NC / MgO）。溶解氧化镁后，首次合成了比表面积为1300–1400 m ² g ^–1的N-石墨烯。N-石墨烯的合成已经通过电子显微镜，X射线衍射和X射线光电子能谱表征。
