Carbon Source Temperature Catalyst Product
Ethylene 5450C -9000C Ni/Fe/Co SWCNT and MWCNT
Hydrogen and Methane 10000catalyst decoposition Co/Ni/Fe On MgO High yield of SWCNT
Acetylene 6000C Cobalt SWCNT and MWCNT
Carbon source with oxide >8000C H2 /CH4 atmosphere, any metal catalyst Composite powders containing CNT
CH4 >5000C Decomposition Metal Catalyst CWNT (major)

MWCNT (minor) | |Any carbon sourceEg. acetylene |>6000C |C/zeolite catalyst | Fullerene+SWCNT+ Few MWCNT|
