Abstract
Graphene can be produced from the byproducts formed during electrolysis of coal. These byproducts may be electrolyzed coal particles, gelatinous film formed on the electrolyzed coal particles, or the electrolyzed coal particles together with the gelatinous film. The electrolyzed coal byproduct is deposited as a thin layer onto a surface, or carrier substrate, which is heated to a temperature effective to form graphite while a reductant gas, such as hydrogen, flows over the heated coal product. The reductant gas flow carries the carbon particles and deposits them onto a surface, forming a layer of graphene thereon.
