摘要

We have performed a series of ab initio molecular orbital and molecular dynamics calculations to ascertain the influence of an endohedral noble gas atom on the reactivity of the surface of the model system C _(70)O _3. Our simulations show that the minimum energy pathways for the ozone ring-opening reaction are influenced by the presence of the endohedral atom. The effect is isomer dependent, with the enthalpy of the reaction increasing for a,b-C _(70)O _3 and decreasing for e,e-C _(70)O _3 when doped with the heavy noble gas atoms Xe and Rn.
