We performed standard and van der Waals-corrected density functional theory
calculations to investigate the hydrogen storage capacity of a phase of
borophene with Pmmn symmetry and nonzero thickness. This borophene
sheet (Pmmn8) has 8 atoms in its unit cell and is more stable than the
planar sheet and that the corrugated Pmmn2 sheet (2 atoms in the unit
cell). Our results show that, in pristine form, the Pmmn8 sheet is not suited
for hydrogen storage applications. However, decoration with Li atoms and
strain increase the hydrogen storage ability of the sheet. We performed also
a detailed quantum chemical topological analysis that shows that the B-Li
interaction in the hydrogenated Li-decorated Pmmn8 sheet is ionic. Our
results for the adsorption of H2 on the Li-decorated Pmmn8 sheet are compared
with those obtained for the adsorption of H2 on Ti-decorated zigzag
graphene nanoribbons.
