“…The use of metal alloys as catalysts (Fe/Ni, Ni/Co, Fe/Co) allows greater control over the nanotubes diameters, purity and type (SWCNT, DWCNT, MWCNT) (20)(21)(22). Few studies have been conducted to evaluate the formation of Fe, Ni and Co alloys with non-standard metals (e.g., Zn, Dy, Pb) as catalysts for the synthesis of carbon materials.…”

Systematic studies to investigate binary catalysts combining the well-established standard transition metals Fe, Co and Ni with less used metals such as Al, Pb, Dy, Gd, Ga and Zn were explored in supported catalyst chemical vapor deposition. The findings show different carbon nanostructures can be obtained depending on the choice of catalyst mix. Comparative studies with Al as a co-catalyst with Fe or Co or Ni were explored in a laser evaporation reactor in both a pure nitrogen environment and a nitrogen environment with additional hydrogen present. The addition of hydrogen etches amorphous carbon leading to cleaner samples. In terms of the obtained carbon nanostructures, the variations among the different binary catalysts were the same for both synthesis routes investigated.
