We present a small set hypothetical zeolite frameworks that are structurally related to faujasite. They are found by examination of the -t nets of the Frank-Kasper phases, which optimize the conditions for regular-tetrahedral nets. The new frameworks have plausible framework energy, as estimated by empirical potential in the GULP program. One of the new frameworks, fav, has framework energy, as a pure silicate, that is only slightly higher than faujasite itself. These present appealing zeolite synthesis targets. |
