摘要
The major structural and vibrational features of TS-1 catalyst have been investigated by means of computational methods based on cluster/embedded cluster approach (ONIOM scheme). This approach has been able to reproduce the perturbation induced on the main structural and vibrational features by NH3 adsorption.
