Multiwall carbon nanotubes (MWNT) growth was performed at 700 °C by catalytic chemical vapour deposition (CCVD) with ethylene as carbon feedstock gas. Different aluminium hydroxides such as gibbsite, boehmite, bayerite were used as Co and Fe supports. The influence of time, gas volume/catalyst mass ratio and catalyst preparation on the carbon nanotubes (CNT) growth was investigated. We have found...
