Analysis reveals optimized catalyst ratios for single-walled carbon nanotube synthesis, indicating significant roles of Fe and Co.

Identifying Fe0.75Co0.25 as a highly efficient catalyst at 850°C, yielding SWCNTs with diameters of 0.9-1.1 nm.
At 600°C, Fe0Co1 demonstrated greater catalytic activity, forming SWCNTs with reduced diameters of about 0.6-0.9 nm.
Molecular dynamics simulations corroborate that catalyst composition significantly impacts the structure of Fe-Co clusters.
Transmission electron microscopy shows high SWCNT yields linked to uniformly sized catalyst particles with surface-segregated Co.
