Hello, I think that will produce a toxic gas by the reaction of graphene with N2.

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.

But how would this influence the question about nitrogen fixation?

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?
