The MTT and TON zeolites also form intergrowths of practical interest. Both zeolites have one-dimensional medium-sized pores and can be synthesized in the aluminosilicate form. The slight differences in pore sizes of MTT and TON could lead to membranes with high shape selectivity, as has been observed for the MEL/MFI case. However, the synthesis of an MTT/TON intergrowth is typically performed by using the dual-OSDA approach, hindering the control of phase fraction. However, fine-tuning the synthesis conditions may direct the formation of these zeolites and the corresponding intergrowth. Although synthesis parameters cannot be selected purely through simulations, past literature outcomes and machine learning models trained on them may guide the exploration of synthesis routes. Interestingly, since MTT has a slightly smaller unit cell than TON, variations of binding energy with respect to shape depend on the commensurability of the OSDA within the framework (Fig. ). At a value of 4 Å for Finally, we show that the method can also be applied to large-pore, three dimensional zeolites. One example is the BEC/ISV intergrowth, which is often only obtained in the presence of germanium or fluoride in the synthesis media. Despite the challenge usually associated to predicting OSDAs for zeolites with intersecting pores, the design principles successfully recover the literature results for phase selectivity in BEC and ISV. Figure shows the proposed OSDAs for the synthesis of this intergrown structure. Reference OSDAs for the selective synthesis of BEC are indeed more favorable towards this framework compared to ISV (Fig. ). Furthermore, the red area towards OSDAs with longer Axis 1 in Fig. recover the fact that longer OSDAs favor BEC zeolite, since the unit cells of BEC and ISV have very similar a and b lattice parameters, but ISV has a c lattice parameter 1% smaller than the c in the BEC unit cell. Similarly to the MTT/TON example, this indicates that the commensurability between the OSDA and the zeolite is a useful parameter when predicting phase selectivity. From these insights and the results from Fig. , we suggest that OSDAs with an Axis 1 between 9 and 10 Å lie in the phase boundary between BEC and ISV, and could be used to direct a zeolite intergrowth.
