N2 - The huge molecular cluster {Fe30Mo72} has been used as a source of catalyst nanoparticles in catalytic chemical vapour deposition (CCVD) process of carbon nanotubes (CNTs) synthesis. Thermal decomposition of {Fe30Mo72} in air is shown by X-ray diffraction analysis to produce iron molybdate, which is converted to alloyed Fe-Mo and Fe nanoparticles at elevated temperature and reduction environment. These nanoparticles supported on MgO, catalyse the growth of single-walled, double-walled and/or multi-walled CNTs depending on the active metal loading and ratio of methane and hydrogen in the feedstock. The structural parameters of the products are studied by transmission electron microscopy and Raman spectroscopy. The best CNT samples are tested as field electron emitters.
