Abstract

See full text

The present invention relates to a catalyst composition for the synthesis of multi-walled carbon nanotube having high apparent density in a manner of high yield. More particularly, this invention relates to a multi-component metal catalyst composition comprising i) main catalyst of Fe and Mo, ii) inactive support of Al and iii) optional co-catalyst at least one selected from Co, Ni, Ti, Mn, W, Sn or Cu. Further, the present invention affords multi-walled carbon nanotube having 5˜15 nm of fibrous diameter and 0.5˜4 μm bundle diameter.
