The confinement effect on the adsorption and reaction mechanism of unsaturated aliphatic, aromatic and
heterocyclic compounds on H-ZSM-5 zeolite has been investigated by the four ONIOM methods (MP2:M06-2X),
(MP2:B3LYP), (MP2:HF), and (MP2:UFF). The H-ZSM-5 ‘nanoreactor’ porous intersection, where chemical
reactions take place, is represented by a quantum cluster of 34 tetrahedral units. Ethene, benzene, ethylbenzene, and
pyridine are chosen to represent reactions of various adsorbates of aliphatic, aromatic and heterocyclic compounds.
Among the four combined methods, (MP2:M06-2X) outperforms the others.
