Atomic vacancies in graphene are created under relatively low energy electron bombardment, but the formation of vacancies is significanlty enhanced by iron nanocatalysis. The evolution of the overall process involves nanoparticle agglomeration, interlayer migration, and confinement to nearby defects. The catalytic activation of metal nanoparticles via elecron irradiation on graphene-like surfaces appears to be a novel process that can be used to obtain porous graphene sheets with high surface areas.
