▎ 摘　　要

NOVELTY - Producing chemically pure non-oxidized graphene nano- sheet, comprises preparing a solution of various natural or synthetic graphite particles in distilled water, mechanically treating the solution, maintaining the size of various graphite particles substantially similar, causing the solution to circulate in the cavitation reactor, applying acoustic energy and electromagnetic energy to the solution and separating the graphene nano- sheet from the solution. USE - The method is useful for producing chemically pure non-oxidized graphene nano- sheet. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for device comprising a reactor vessels, multiple electromagnetic emitters, resonator having many input openings and multiple acoustic emitters. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the device utilized in the above mentioned method.
