A second passivation and a multistage carbon‐source supply (CSS) allow a 50‐fold enhancement of the growth rate of large single‐crystalline graphene with a record growth rate of 101 μm min −1 , almost 10 times higher than for pure copper. To this end the CSS is tailored at separate stages of graphene growth on copper foil, combined with an effective suppression of new spontaneous nucleation via second passivation.
