Abstract
We describe our nascent facility for the mass production of high-quality, multi-layer, turbostratic graphene via an explosion aerosol synthesis. The facility occupies ca. 12,500 ft² including a production area, laboratory and office space. We have scaled up our original bench scale explosion reactor to an automated production device for graphene. The device produces approximately one kilogram per hour with a 3.5m² footprint. The reaction that makes the graphene is exothermic, unlike any other method to make graphene. Hence, it is much more energy efficient than other production method. Our production method has been certified by the international Graphene Council. Our facility also has two 2000L stirred reactors for the production of core-shell graphene oxide via a Fenton oxidation of the graphene we make. The graphene oxide has no intercalated oxygen, unlike every other graphene oxide, and has a homogeneous reactive shell of carboxylic acid groups. Thus an uncompromised graphene can be rationally targeted via chemistry to a wide variety of application.
