Synthesis and hydrogenation behaviour of single walled carbon nanotubes
SWNTs were grown by thermal decomposition of methane at a temperature of 900 degrees Celsius over Fe/Co metal particles dispersed on a MgO support. SWNTs were characterized by SEM and TEM analyses, X-ray diffraction and Raman spectroscopy measurements. The hydrogenation behaviour of raw material and of samples produced with different methods were investigated by thermogravimetric techniques at pressures up to 10 bar and different temperatures. A high pressure volumetric apparatus was also designed for measuring H2 storing capacity of nanotubes from room down to liquid nitrogen temperatures.
