Description
Summary:The present experimental study reports on hydrogen desorption behavior of hydrogenated single-walled carbon nanotubes (SWCNTs), functionalized with borane (BH 3 ). Desorption is carried out using a thermal annealing technique. The hydrogenated samples are annealed at 200 ° C for 30 min and characterized using Fourier transform infrared (FTIR) and Raman spectroscopy studies. The amount of released hydrogen is measured by thermogravimetric/thermal desorption spectroscopy (TG/TDS) studies. FTIR and Raman studies confirm the desorption of hydrogen. The TG/TDS results reveal that 100% of stored hydrogen is released in approximately 1.5 min in the temperature range 100-150 ° C.
