“…Hydrogen storage in nitrogen-doped graphene is a subject of active research and shows potential for improving hydrogen storage capabilities. 105 Nitrogen (N) doping involves introducing N atoms into the graphene lattice, which can modify its physical and structural properties. 106 Three types of bonding can occur when nitrogen is doped into graphene, i.e., graphitic N, pyridinic N, and pyrrolic N. Several experimental and theoretical investigations reveal that nitrogenated graphene is a remarkable approach for hydrogen storage.…”
