Investigation of water-assisted synthesis of high quality carbon nanotubes

Multiwall carbon nanotubes (MWNTs) were synthesized using a water-assisted method. High quality MWNTs having inner and outer diameter in the range of tens of nm and length in the range of hundreds of nm were obtained. The characterization results (SEM micrographs) clearly show that yield as well as nature (straight or twisted and curled) of produced carbon nanotubes varies directly with the diameter of initial carbon based precursor.
