Theoretical insight into the BH3·HCN adsorption on the Co(100) and Co(110) surfaces as hydrogen storage

Abstract

Fifteen configurations and adsorption energies of the adsorption sites of BH∙∙∙HCN on Co(100) and Co(110) surfaces were investigated using the density functional theory. The results show that after BH∙∙∙HCN is adsorbed, although there is no general behavior for the H∙∙∙H distances, the adsorption energies of BH∙∙∙HCN are always far stronger than those of H on Co surfaces, suggesting that the dihydrogen-bonded complex, one kind of prospective material for reversible hydrogen storage, can be tightly adsorbed on the surfaces of metals. Thus, the attempts to store the significant amounts of H can be successful by the way that the dihydrogen-bonded complexes are adsorbed on the surfaces of metals. The stability and binding mechanism was analyzed by the Mulliken charge population and reduced density gradients (RDGs) methods. Graphical Abstract BH···HCN adsorption on Co surface.

“…Vander Waals force and steric constant is clearly indicated at green and red color [60,61]. RDG interactions like hydrophobic interaction, Vander Waals force, dipole-dipole interaction, iondipole interaction, pi-stacking and hydrogen bond interaction of the titled compound was docked with DIDA and RNA (protein).…”

“…The reduced density gradient is directly proportional to the electronic density of the molecule. Which means a small reduced density gradient is low electronic density [88][89][90][91][92]. Figure 9 shows the reduced density gradient for tucatinib.…”
