Reactor for continuous production of graphene and 2D inorganic compounds

A continuous reactor or reactor system for producing an inorganic 2-D compound, said reactor comprising:

• A) a first body comprising an outer wall and a second body comprising an inner wall, wherein the inner wall defines a bore and the first body is configured within the bore and wherein a motor is configured to rotate the first and/or second body;
• B) a reaction chamber being configured between the outer wall of the first body and the inner wall of the second body;
• C) a first inlet and a second inlet disposed at or near a first end of the reactor and being configured to be in fluid communication with the reaction chamber;
• D) a first outlet and a second outlet disposed downstream from said first and second inlet at or near a second end of the reactor, the first outlet and the second outlet being configured to be in fluid communication with the reaction chamber;
• and
• E) a flow return conduit having a first conduit inlet in fluid communication with the second outlet of the reactor and having a first conduit outlet in fluid communication with the second inlet of the reactor;
• wherein said reactor or reactor system is operated to receive a first stock of reactants, containing an inorganic layered compound dispersed in a liquid medium, through the first inlet into the reaction chamber, driving the reactants downstream toward said first and second outlet and facilitating reactions between the reactants to produce a first product slurry, driving the first product slurry through the flow return conduit and the second inlet of the reactor to re-enter the reaction chamber, and further driving the first product slurry downstream toward the first and second outlet to form a second product slurry, which is discharged off the reaction chamber through the first outlet of the reactor or driven to flow through the conduit to return to the reaction chamber through the second inlet for at least another time, wherein the inorganic layered compound is selected from boron nitride (h-BN), HfS2, tungsten disulfide (WS2), NiTe2, VSe2, WSe2, molybdenum disulfide (MoS2), MoSe2, MoTe2, TaS2, RhTe2, PdTe2, NbS2, NbSe2, NbTe2, TaSe2, Bi2Se3, Bi2Te3, or a combination thereof.
