铜虫 (小有名气)

The hydrogen recombination reaction, H + H f H2, and the hydrogen exchange reaction, H + H2f H2 +
H, taking place inside single-walled carbon nanotubes have been studied by using quantum mechanics molecular
dynamics simulations. Two types of hydrogen exchange reactions have been found. The fast reaction lasts in
less than 5 fs, and the slow one lasts for about 40 fs with a clear intermediate state manifested. The collisional
reaction for two H atoms to form a H2 molecule usually takes place in a time interval of 25 fs. We also
describe the detailed process of the reaction of individual H atoms to form H2 molecules and, with an increase
of the density of H2 molecules confined in the tubes, H2 molecular condensation to form clusters and finally
to form condensed H2 molecular lattices.
