Was just looking up some papers on growing carbon nanotubes..was wondering why the catalyst used are always either iron/nickel/cobalt/moly, or their derivatives like ferrocene etc..why not copper or aluminum? most published papers just skirt this issue...does anyone here know?
It is possible that these other metals are not suitable as catalysts.
As a result, there won't be any use of them, and there will be little explanation of why these metals aren't used.
So, the implication that the area is "skirted" may not be accurate. The area may be "ignored" because it isn't fruitful.

very true...carbide forming capability must be essential...but silicon, copper etc. do form carbides...but why arent they used? anyways..thanx for your interest...it would be great if you could refer me to some place where thers mention of the surface chemistry which eliminates other metals....
