Abstract
A process of controlling the morphology of graphite in a process for the production of graphite, the process comprising: contacting at elevated temperature, a metal-containing catalyst with a hydrocarbon gas to catalytically convert at least a portion of the hydrocarbon gas to hydrogen and carbon; wherein the temperature is between 600° C. and 1000° C. and a pressure between 0 bar(g) and 100 bar(g), and wherein both the temperature and the pressure are set within predetermined value ranges to selectively synthesise graphitic material with a desired morphology.

A process comprising:
- contacting at elevated temperature, a naturally occurring polycrystalline iron oxide catalyst with a hydrocarbon gas to catalytically convert at least a portion of the hydrocarbon gas to hydrogen and carbon;
- wherein the temperature is between 600° C. and 1000° C. and a pressure is between 1 bar(g) and 10 bar(g), to selectively synthesise graphitic material with a morphology selected from the group of carbon nano-onions (CNOs), carbon micro-shells (CMSs) and graphene.
