Method for manufacturing graphene film on molybdenum-based substrate

The invention relates to a method for manufacturing a graphene film on a molybdenum-based substrate, which comprises the following steps of: putting a molybdenum catalyst in an anoxic reactor, and increasing the reaction temperature of the catalyst to 500-1600 DEG C; introducing a carbonaceous gas into the anoxic reactor, reacting for 0.1-9999 min at 0.1-760 torr, and cooling the furnace temperature to room temperature to obtain the molybdenum-based substrate with a graphene film; and removing the molybdenum catalyst to obtain the graphene film. The method provided by the invention has high repeatability and is simple and feasible; and the obtained graphene film has the characteristics of large area, controllable layer number and uniform distribution.
