NOVELTY - Production of graphene comprises selecting metal foil substrate, adding foil substrate to chemical vapor deposition reaction furnace, adding helium at 400-600 standard cubic centimeters per minute (SCCM), adding copper substrate, heating at 900-100- degrees C for 40-50 minutes, adding helium at 500-800 SCCM, reacting at 900-100 degrees C under hydrogen and methane gas at flow ratio of 1:1-100 for 50-70 minutes, and cooling at 10 degrees C to 500-600 degrees C for 60 minutes. USE - Method for producing graphene. ADVANTAGE - The simple and inexpensive method ensures high product purity.
