Abstract
The present invention relates to a catalyst composition for the synthesis of thin multi-walled carbon nanotube(MWCNT). More particularly, this invention relates to a multi-component metal catalyst composition comprising i) main catalyst of Co and Al, ii) inactive support of Mg and iii) optional co-catalyst at least one selected from Ni, Cr, Mn, Mo, W, Pb, Ti, Sn, or Cu. Further, the present invention affords thin multi-walled carbon nanotube having 5˜20 nm of diameter and 100˜10,000 of aspect ratio in a high yield.
