1. A method for producing a carbon nanomaterial (CNM) product, the method comprising steps of:
(a) heating an electrolyte media to obtain a molten electrolyte media;
(b) positioning the molten electrolyte media between an anode and a cathode of an electrolytic cell;
(c) introducing a source of carbon into the electrolytic cell;
(d) introducing an iron-free, nickel and chromium containing additive into the electrolyte media before the step of heating or introducing the iron-free, nickel and chromium containing additive into the molten electrolyte media, wherein the iron-free, nickel and chromium containing additive is added in an amount of between 0.05 wt % and 2 wt %, relative to the amount of the electrolyte media or the molten electrolyte media;
(e) applying an electrical current to the cathode and the anode in the electrolytic cell; and
(f) collecting the CNM product from the cathode, wherein the CNM product comprises a minimum relative-amount of between 50 wt % and 99 wt %, relative to a total weight of the CNM product of a nano-carbon bamboo.
