A method is disclosed for making graphenic carbon particles. The method includes introducing a hydrocarbon precursor material capable of forming a two-carbon-fragment species into a thermal zone, heating the hydrocarbon precursor material in the thermal zone to form the graphenic carbon particles from the hydrocarbon precursor material, and collecting the graphenic carbon particles. Apparatus for performing such a method, and graphenic particles produced by the method, are also disclosed.
