AB We performed standard and van der Waals-corrected density functional theorycalculations to investigate the hydrogen storage capacity of a phase ofborophene with Pmmn symmetry and nonzero thickness. This borophenesheet (Pmmn8) has 8 atoms in its unit cell and is more stable than theplanar   sheet and that the corrugated Pmmn2 sheet (2 atoms in the unitcell). Our results show that, in pristine form, the Pmmn8 sheet is not suitedfor hydrogen storage applications. However, decoration with Li atoms andstrain increase the hydrogen storage ability of the sheet. We performed alsoa detailed quantum chemical topological analysis that shows that the B-Liinteraction in the hydrogenated Li-decorated Pmmn8 sheet is ionic. Ourresults for the adsorption of H2 on the Li-decorated Pmmn8 sheet are comparedwith those obtained for the adsorption of H2 on Ti-decorated zigzaggraphene nanoribbons.
