Graphene production by dissociation of camphor molecules on nickel substrate

► An inexpensive chemical vapor deposition method based on camphor is presented. ► Few-layer graphene carpets of high quality are produced on polycrystalline Ni. ► The working deposition temperature is decreased by about 15%. ► Natural cooling is employed for graphene production. ► Role of Ni surface texture upon the graphene growth process is demonstrated.
