氢分子在石墨烯上吸附的密度泛函研究

Density Functional Study of adsorption of molecular hydrogen on graphene layers

J. S. Arellano, L. M. Molina, A. Rubio, J. A. Alonso

摘要:

密度泛函理论已被用于研究分子H2在石墨烯层上的吸附。考虑了碳原子顶部、碳原子与碳原子之间的键和碳原子六边形中心的不同吸附位置,并进行了比较。我们得出结论,H2的最稳定的配置是物理吸附以上的六边形的中心。然而,经典扩散的障碍非常小。

英文摘要:

Density functional theory has been used to study the adsorption of molecular H2 on a graphene layer. Different adsorption sites on top of atoms, bonds and the center of carbon hexagons have been considered and compared. We conclude that the most stable configuration of H2 is physisorbed above the center of an hexagon. Barriers for classical diffusion are, however, very small.
