1. a kind of preparation method of Graphene, it is characterised in that:

  • More than 90% is accounted for 200 mesh particles by pure magnesium powder levigate, will be groundMagnesium powder after thin is placed in ceramic ware after being mixed with NaCl, and carbon tetrachloride liquid is added in another ceramic ware, then by twoThe ceramic ware of dress raw material is put in vacuum drying oven, is vacuumized, is made atmospheric pressure in vacuum drying oven in below 10Pa, be warming up to vacuum drying oven500 ~ 550 DEG C, simultaneously there is reduction reaction with magnesium powder in carbon tetrachloride gasification, the reaction time is 1-3h, and product is molten with hydrochloric acidSolution, suction filtration obtain Graphene.
