Following the game-changing high-pressure CO (HiPco) process that established first facile route toward large-scale production of single-walled carbon nanotubes, synthesis cm-sized graphene crystals ultra-high purity grown during tens minutes is proposed. The Boudouard reaction serves for time to produce individual monolayer structures on surface a metal catalyst, thereby providing chemical vapor deposition technique free from molecular and atomic hydrogen as well vacuum conditions. This approach facilitates inhibition nucleation CO/CO2 mixture maintains high growth rate seeds reaching monocrystals. Unique features coupled with CO-driven catalyst engineering ensure not only suppression second layer but also provide simple reliable cleaning. Aside being novel source, monoxide ensures peculiar modification in general opens avenues breakthrough graphene-catalyst composite production.
