[en] Functionalization of borane onto MWCNT (MWCNT+BH₃) complex is synthesized by drop casting method and its hydrogen storage capacity is investigated. The hydrogenation of MWCNT+BH₃ complex is studied using purpose built apparatus at 100°C under 5 bar pressure of H₂ for about 15 min. Hydrogen desorption studies is carried out with the help of thermogravimetric analyzer under nitrogen environment. The vibrational bands centered at 1089 and 2359 cm^-1 due to the deformation and asymmetric stretching modes of B-H bonds. The peak at around 2900 cm^-1 due to the vibrational mode of C-H bond. The surface morphology and the presence of C, B and O is confirmed by SEM and EDX analysis. Further, thermal stability and hydrogen adsorption/desorption studies will be analyzed. (author)
