摘要：

A mixed quantum mechanics/molecular mechanics (QM/MM) model is used for investigating the nature of molecular hydrogen adsorption in pure and alkali-metal-doped single-walled carbon nanotubes (SWNTs). Our results demonstrate that the charge transfer from the alkali metal to the tube polarizes the H-2 molecule and this charge-induced dipole interaction is responsible for the higher hydrogen uptake of the doped tubes.
