Abstract

See full text

Provided is a process for manufacturing a graphene material, the process comprising (a) injecting a rust stock into a first end of a continuous reactor having a toroidal vortex flow, wherein the first stock comprises graphite and a non-oxidizing liquid (or, alternatively, graphite, an acid, and an optional oxidizer) and the continuous flow reactor is configured to produce the toroidal vortex flow, enabling the formation of a reaction product suspension or slurry at the second end, downstream from the first end, of the continuous reactor; and (b) introducing the reaction product suspension/slurry from the second end back to enter the continuous reactor at or near the first end, allowing the reaction product suspension/slurry to form a toroidal vortex flow and move down to or near the second end to produce a graphene suspension or graphene oxide slurry. The process may further comprise repeating step (b) for at least one time.
