摘要：
A study on the effect of the metal-support interaction by employing iron particles supported on magnesium oxide (MgO) nanopowder in an alcohol-CVD process for single-walled carbon nanotubes growth is presented. Upon the prolongation of the process time, three main observations were detected: (i) decrease of the mean nanotubes diameter, (ii) reduction of the diameter distribution by the factor of two, (iii) increase of relative purity of the samples.
