A fast transfer-free synthesis of a graphene structure can be successfully achieved by Ni-catalysed transformation of amorphous carbon (a-C) during rapid thermal processing, but the role of the a-C structure in the a-C-to-graphene transformation is still unclear.

The fast formation of defective graphitic C structures and the easy evaporation of surplus Ni atoms with excess C atoms are likely attributed to the formation of a viscous-liquid-like Ni–C solution and the faster diffusion of C atoms in Ni at 1200 K.
