Carbon materials,especially graphene and carbon nanotubes,have attracted much attention during the recent years.In order to the application of graphene in catalysis,various methods have been taken to modify the properties of pristine graphene.Graphene containing nitrogen species has been proved an efficient material in catalysis and supporting nanoparticles.In this study,we systematically investigated the role of two types of nitrogen[1-4],including lattice doped and “external” nitrogen,in a series of reactions and supporting metal nanoparticles mainly by means of density functional theory calculations.Our study shows that the role of “external” nitrogen in the modification of graphene is similar with “doped” one.
