N1 - Funding Information:
The calorimetric studies at UC Davis were supported by the Fluid Interface Reactions, Structures and Transport (FIRST) Center, an Energy Frontier Research Center funded by the U.S. Department of Energy , Office of Science and Office of Basic Energy Sciences under Award Number 4000134953 . We acknowledge financial support from the Spanish Ministry of Economy and Competitiveness through MAT2017-86616-R grant and the “Severo Ochoa” Programme for Centres of Excellence in R&D (SEV-2015-0496). We thank Gustavo Costa for helpful suggestions concerning the measurements. The XPS data were acquired at the Laboratorio de Microscopías Avanzadas (LMA) - Instituto de Nanociencia de Aragón (INA).

N2 - The thermodynamic stability of a series of nitrogen - doped reduced graphene oxides prepared by ammonolysis of graphene oxide has been investigated by high temperature oxidation calorimetry. In terms of enthalpy and depending on the concentration of nitrogen, the nitrogen - doped reduced graphene oxides can be up to 73 kJ·mol−1 more stable than graphite plus nitrogen. There is a linear relationship between the nitrogen content and the formation enthalpy, which indicates a decrease in stability with increasing nitrogen content.
