Graphene is a potential "miracle" material with superior properties of tensile strength, thermal and electrical conductivity, and corrosion resistance. Current graphite-based production processes result in very high priced graphene (a gram of graphene oxide can cost over $150), which acts as barrier for commercial exploitation of this remarkable material. Our innovative one-pot process using abundantly available coal as a raw material is at least an order of magnitude cheaper, is simpler, uses one acid vs many strong acids and oxidants, and produces significantly less hazardous waste.
