• used to synthesize boron nitride nanotubes (BNNT)s [3][4]. BNNTs, structural analogoues of carbon nanotube (CNT)s, have superior properties than CNTs due to their robust structure which resists high temperatures and harsh chemical conditions. They also have a high hydrogen storage capacity due to the

• ionic nature of the B–N bond [5]. In contrast to CNTs, the BNNTs have a constant and wide band-gap of 5.5 eV. Therefore, they are electrical isolators independent from their size or chirality. In recent studies, it has been indicated that the hydrogen storage capacity of BNNTs is two times greater than
