Abstract
Large scale production of multiwall carbon nanotubes (MWCNTs) has been achieved by a solution method. A heated bubble chamber is used as a hydrocarbon source from liquid n-hexane, and a Fe catalyst precursor is prepared by Fe(CO)5 which is dissolved into the n-hexane. The temperature and dissolved Fe concentration in the n-hexane have influences on the synthesis of MWCNTs. The synthesized MWNTs are collected by an electromagnet. SEM shows the diameters of MWNTs are in the range of 20-60 nm and are several micrometres in length.

Keywords: Carbon nanotubes, Solution method, Carbon nanotubes mass production.
