Abstract 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 –NH 2 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.
