Chirally selective synthesis of single walled carbon nanotubes on novel catalysts

Single-walled carbon nanotubes (SWCNTs) have excellent electronic, thermal, optical, and magnetic properties, which depend on their specific (n,m) structure; therefore precise control of SWCNT (n,m) structure is crucial to realize their potential applications. So far, a few catalysts can achieve selective synthesis of SWCNTs with a narrow (n,m) distribution; however, most of the chiral-selective growth is restricted to one or two small diameter SWCNTs, such as (6,5) and (7,5) nanotubes (d
