Effect of Molecular Interaction Towards Homogenous Diameters for Synthesized MWCNTs from Methanol/Butanol mixture by CVDs

摘要

Carbon nanotubes with multi-wall (MWCNT's) with homogenous diameters were successfully synthesized from (1:1) Methanol/Butanol by chemical vapor deposition (CVD) at 700°C using Fe as a catalyst. The mixture of alcohol includes low ratios of amorphous carbon with high ratios of carbon atoms which are able to covert for MWCNTs. The product was characterized by XRD, Raman spectroscopy, SEM and EDX analysis shows the formation of carbon nanotubes MWCNT's. The diameter of tubes shows semi-equal value when arrange between 90-105nm and the homogeneous length reached to more than 8 um. The molecular interaction for the mixture of C1/C4 alcohol plays an important role towards the reduction and changing the skeleton of the agglomerations for the molecules at vapor phase.
