Another production method is called chemical vapor deposition, or CVD, and that's where scientists take a gas of hydrocarbons along with a metal catalyst and are able to remove the hydrogen atoms from the hydrocarbon, then keep only the carbon atoms and then hopefully these carbon atoms kind of arrange themselves side by side into this graphene lattice form.
