The Stability

The hydrogen-rich compound ( H 2)n CH 4 (for n = 1, 2, 3, 4) or for short ( H 2)n M is one of the most promising hydrogen storage materials. The ( H 2)4 M molecule is the best hydrogen-rich compound among the ( H 2)n M structures and it can reach the hydrogen storage capacity of 50.2 wt.%. However, the ( H 2)n M always requires a certain pressure to remain stable. In this work, we first investigated the binding energy of the different structures in ( H 2)n M and energy barrier of H 2 rotation under different pressures at ambient temperature, applying ab initio methods based on van der Waals density functional (vdW-DF). It was found that at 0 GPa, the ( H 2)n M is not stable, while at 5.8 GPa, the stability of ( H 2)n M strongly depends on its structure. We further investigate the Raman spectra of ( H 2)n M structures at 5.8 GPa and found the results were consistent with experiments. Excitingly, we found that boron nitride nanotubes (BNNTs) and graphite and hexagonal boron nitride ( h - BN ) can be used to store ( H 2)4 M , which give insights into hydrogen storage practical applications.

Single Source Precursor

An efficient chemical vapor deposition (CVD) method was successfully utilized to synthesize boron nitride nanotubes (BNNTs), where Ammonium boron trifluoride (NH3BF[Formula: see text] and MgCl2 were employed as the novel single-source precursor and the promoter, respectively. The as-obtained BNNTs displayed a collapsed structure with the average diameter of 15[Formula: see text]nm and lengths up to tens of micrometers, named as collapsed BNNTs. They exhibited a reproducible hydrogen storage capacity of 2.63[Formula: see text]wt.% under 10 MPa and at ambient temperature. Moreover, they showed an high storage cycling stability due to the excellent chemical and structural stability.
