N‐doped carbon nanostructures have gained attention as an alternative electrocatalyst for diverse reactions. They are making attractive the scalable methods to achieve enough material. However, optimizing appropriate nitrogen species in graphitic electrocatalysts is critical. Here, N‐doping process obtain graphene starting from oxide (GO) precursor contributing toward this goal explored. The role of doping temperatures and times on incorporation into sheets, subsequent desorption, influence oxygen (O) GO during analyzed. experimental evidence combined with first‐principles density functional theory calculations understand key characteristics process, particularly emphasizing proportion N obtained. Finally, critical sensitivity proportions present illustrated by evaluating activity selectivity reduction reaction a set three different samples designed.
