摘要:
The present invention relates to a catalyst composition for the synthesis of thin multi-walled carbon nanotube (MWCNT) and a method for manufacturing a catalyst composition. More particularly, this invention relates to a multi-component metal catalyst composition comprising i) main catalyst of Fe and Al, ii) inactive support of Mg and iii) optional co-catalyst at least one selected from Co, Ni, Cr, Mn, Mo, W, V, 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.
