摘要：
Large cluster models of Na- and H-mordenite zeolites (MOR) have been used to analyze the structural and energetic properties of these zeolites, in particular the effect of the Aluminum site on the framework - cation binding energies. The most populated T3, T4 and T1 Al sites have been investigated. The calculations were performed within the framework of Density Functional Theory (DFT), using both the local (LDA) and the generalized gradient approximation (GGA) and all-electron basis sets. The properties are compared with experiment.
