NOVELTY - Producing large-scale low-layer graphene (FLG) with high degree of defects from graphite by high-energy ball milling by dry oscillating motion involves precursor is graphite in flake form with a length between 2 and 50 pm and a thickness of less than 100 nanometer. The grinding is carried out in a metal container covered with a material that has a Knoop hardness greater than 1,000 kg/mm2 in the presence of balls of the same material with an oscillation frequency between 1,000 and 1,500 revolutions per minutes and a mass ratio between the ball or balls and the graphite used between 1:20 and 1:30. USE - Method for producing large-scale low-layer graphene (FLG) with high degree of defects from graphite by high-energy ball milling by dry oscillating motion used in used in multidisciplinary technological fields such as catalysis. ADVANTAGE - The method enables to produce large-scale low-layer graphene (FLG) with high degree of defects from graphite by high-energy ball milling by dry oscillating motion that has industrial scalability, and high degree of defects with great chemical stability.
