Graphene does not have functionalities by which this process can happen, that is graphene is meant to be defect free. On the other hand if you use a functionalized graphene (i.e. graphene with defects) this is a possibility as the paper referred to by Alwin David Samuel shows.
Well.. I understand that nobody have shown direct evidence of the presence of graphene in micron size. The samples referred as graphene in the literature may be thin graphite (1~100 nm thick) rather than monolayer graphene because I could not see HRTEM and Raman (radial mode signal) data, which provide direct evidence for the presence of mono- or bi-layer graphene. Please see the paper, Lee et al. Raman Radial Mode Revealed from Curved graphene, J. Phys. Chem. Lett, 8, 2597-2601 (2017), to know how to identify mono- or bi-layer graphene.
Yes, I hope a scientist saves his valuable time. One may do useless works if one does not confirm the material first, graphene. Who is interesting in N fixation onto graphite?
