text: Although the effects of the zeolite topologies and Al contents on the energetics of zeolites have been reported experimentally, (20, 22) the large-scale, systematic establishments of such relations for all zeolite topologies with a wide range of Si/Al ratios and various Al distributions experimentally are impossible because the available Si/Al ratios of existing aluminosilicate zeolites are generally limited to a certain range depending on their topologies.
