摘要:
A method of producing a carbon nanotube product comprising a catalytic particle and carbon nanotubes deposited thereon. The catalytic particles preferably contain Co or Ni metal from Group VIII, and Mo or W metal from Group VIb. The catalytic particle preferably comprises a support material upon which the metals are disposed. The carbon nanotube product is preferably formed by exposing the catalytic particle to a carbon-containing gas at a temperature sufficient to form the carbon nanotubes as a primary portion of a solid carbon product with minor amounts of graphite and amorphous carbon residue.

The resistance of a semiconductor nanoparticle provided with a surface treatment, such as an OH coating or ammonia treatment, against external factors is improved. A semiconductor nanoparticle provided with a surface treatment such as an OH coating or ammonia treatment and having high-emission properties is coated with an organic material, such as hexylamine, dodecylamine, trioctylmethylammonium, tridodecilmethylammonium, and similar organic material, by migrating the semiconductor nanoparticle from an aqueous phase to an organic solvent, such as hexane or toluene, thereby providing it with durability against external factors.
