Growing Carbon Nanotubes
admin | Jun 01, 2007 | Comments 14
Very simple method (CVD spray pyrolysis) for producing multiwalled carbon nanotubes at industrial scale. They grow inside a quartz tube at 900° C, from a mixture of ferrocene, toluene and argon gas

Spray-pyrolisis …
Spray-pyrolisis method, a variation of the well known “chemical vapor deposition” (CVD) method. The solution with the catalyst is sprayed inside the quartz tube, which is at 900°C.

It’s not that expensive… In fact the Kg of CNT is getting cheaper every day.
thanks, and how …
thanks, and how much (length) would you get out of that a day? do you think we could use it to make a space elevator?
Could someone …
Could someone please tell me exactly whats going on?
Yes indeed.. a …
Yes indeed.. a macroscopic cable having the same strength-to density
ratio as a single, defect-free nanoscopic CNT would allow
us to build fantastic structures such as a terrestrial space elevator.
that is awesome! i …
that is awesome! i dont mean to be annoying with all these questions but, how much energy would it take to m produce them? and what technique do you use to connect them?
I don’t evaluate …
.
I don’t evaluate their mechanical properties, so I don’t care if they are connected. Although there are several methods to connect them, using electromagnetic fields for instance. I test them for fuel cell catalyst support and for hydrogen production with solar light. I haven’t made an estimation of how much energy the whole process consume… I just use the equipment in the lab
But I’ll do the …
But I’ll do the estimation of the total cost, considering the 900°C of the furnace, the cost of the Argon, the ferrocene, etc… I promise.
thanks!
thanks!
