英文摘要Guest(metal)-zeolite interactions in a two component heterogeneous catalyst have been investigated by high-field and high-speed Al-27 MAS NMR, and two-dimensional Al-27 MQ MAS NMR experiments as well as ab initio DFT methods. It was established that strong interactions between guest and zeolite occur in a metal/zeolite system, with the metal anchored to the tetrahedral aluminum framework site through two oxygen bridges. It disturbs the tetrahedral environment of associated aluminum framework, changing AlO4 geometry from near T-d to C-2v; this enables us to resolve this species from the undisturbed aluminum framework species in high-field Al-27, MAS NMR and two-dimesional Al-27 MQ MAS NMR experiments.
