A method to fabricate carbon fibers or graphene, comprising the steps of: obtaining a precursor material from a hydrocarbon substance from one or both of a waste stream or a fossil fuel source, wherein obtaining the precursor material comprises: separating gases from the hydrocarbon substance to form hydrogen gas and a carbonaceous gas; dehydrogenating the separated carbonaceous gas by adding heat to form a dehydrogenated carbon material; and reacting the dehydrogenated carbon material with a nitrogenous material to produce the precursor material, processing drawing the a precursor material to produce carbon fibers, wherein i) the processing the precursor material drawing causes nitrogen and hydrogen to be released, and ii) the precursor is derived from a hydrocarbon substance from one or both of a waste stream or natural gas.
The method as in claim 4, wherein the produced carbon fibers include a fuzzy fiber structure, a twisted fiber or a flat fiber structure.
The method as in claim 4, wherein the processing the precursor material drawing includes forming an internal nanofiber or a microfiber within the produced carbon fibers.
