Abstract
The adsorption and dissociation of molecular oxygen on the surface of N-graphene/Au/Ni(111) epitaxial system with high crystalline quality of N-graphene have been investigated. The system is formed in such a way that nitrogen impurities in it are exclusively represented by graphitic and pyridinic configurations in equal concentrations. Using X-ray photoelectron spectroscopy and density functional theory calculations, the relationship between the chemical shift of the N 1s core level caused by the adsorption of molecular oxygen and the atomic position of individual oxygen atoms after molecular dissociation has been established.
