Over the 316 stainless steel mesh supported La0.95 Mg0.05 Ni0.8 Co0.2O3 perovskite structured catalyst, undiluted methane was cracked into hydrogen and highly graphitic carbon nano-onions (CNOs) and wheat stalk chains, the former was first produced in cheaper and simpler way and the later was first discovered. The Fe-Cr nano-alloy was responsible for the formation of the CNOs while the Ni or Ni-Fe nano-alloy was for the formation of carbon nano-wheat stalk chains. This process realized the ultimate ideal goal for the natural gas utilization: zero emission, clean hydrogen production, zero waste, and highly valuable carbon recycling. Moreover, the capacitances of the CNOs were evaluated by the cyclic voltammetry at different scan rates. The result indicated the capacitance of the CNOs was higher than that of Vulcan XC-72 carbon black, showing their promising applications in supercapacitors. © 2014 Copyright Taylor and Francis Group, LLC.
