We directly observed unique morphological changes in Cu-doped graphene by aberration-corrected TEM. DFT calculations reveal a reduction of energy barrier that caused rotation of C-C bonds near Cu atoms. Our results suggest that individual Cu atoms can catalyse reconstruction of carbon nanostructures.
