| Abstract | ||
| ARC DISCHARGE method was utilized to synthesize carbon nanotubes ….. (CNTs). The arcing was carried out in air atmosphere in presence of amorphous alloy as catalyst. The current density was maintained constant during the experiment. The amorphous alloys used were CoFeB amorphous alloy and ZrCuNiAl amorphous alloy. Characterization of the samples produced indicates that the presence of CoFeB amorphous alloy much enhanced the yield of multiwall carbon nanotubes (MWNTs). In contrast, the use of ZrCuNiAl amorphous alloy exerted an opposite effect. The produced MWNTs were tested for hydrogen sorption at 20 bar. | ||
