The carbon nanomaterials were prepared using the thermal chemical vapor deposition with ${C_2}{H_2}$ on the Ni-graphite mixture as a supported catalyst. The samples were identified by SEM, TEM, Raman spectroscopy, and the hydrogen storage measurement by electrochemical method was also carried out. The purity of carbon nanotube prepared using ground mixture was higher than that of unground one. Also, the amount of hydrogen storage of purified carbon nanomaterials was more than that of unpurified one.
Key words: Carbon nanomaterials, Mechanochemical treatment, Chemical vapor deposition, Hydrogen storage
