Low temperature heating creates scintillating opportunity in controlling the reaction condition and designing the suitable nitrogen containing graphene oxide (NGO) for material researchers and industrial applications. Herein, one step synthesis of NGO from low temperature heating (≈ 120–125 °C) is reported from a nongraphitic nitrogenous precursor in contrast to the conventional methods using graphitic precursors, oxidizers, and N‐containing dopants. The formation of nanosheets of NGO with high nitrogen content (≈19%) is achieved from 3‐aminophenol in presence of trace amount of air bypassing doping and oxidizing agents. The presence of –NH₂ and –OH in the precursor plays a vital role in the condensation and aromatization. The chemistry of formation of NGO is studied and the mechanism confirms the presence of pyridinic‐N, graphitic‐N, and pyrrolic‐N in the nanosheets. Further urea is used to reduce NGO into reduced nitrogen graphene oxide, retaining the sheet structure.

从3-氨基苯酚一步合成含N的氧化石墨烯

低温加热为控制反应条件和为材料研究人员和工业应用设计合适的含氮氧化石墨烯（NGO）提供了闪烁的机会。在此，与传统的使用石墨前体，氧化剂和含氮掺杂剂的方法相比，从非石墨含氮前体中通过低温加热（约120–125°C）一步合成NGO被报道。在存在痕量空气绕过掺杂剂和氧化剂的情况下，由3-氨基苯酚形成具有高氮含量（约19％）的NGO纳米片。-NH ₂的存在前体中的-OH在缩合和芳构化中起着至关重要的作用。研究了NGO的形成化学过程，其机理证实了纳米片中存在吡啶N，石墨N和吡咯N。另外的尿素用于将NGO还原成还原的氮氧化石墨烯，保持片状结构。
