The morphologies and mesoporosities of hierarchical SSZ-13 zeolites significantly depend on the additive amounts of TPOAC in the synthesis system. Hierarchical SSZ-13-MT-2 zeolite, synthesized with a high molar proportion of TPOAC (<i>x</i>), exhibited aggregate particles assembled from nanocrystals approximately 20 nm in size, along with the largest external surface area and mesoporous volume, reaching 405.7 m²/g and 0.40 cm³/g, respectively. The crystallization evolution mechanism was discussed in detail, revealing that the rapid synthesis and formation of mesoporous structures in the hierarchical SSZ-13-MT-<i>x</i> samples can be attributed to a cooperative strategy involving the conversion from the Y zeolite to SSZ-13 along with the TPOAC-directed synthesis of mesoporous zeolites.

When the macroscopic surface energy remains constant, increased undulations in the microscopic morphology amplify disparities between in-plane and out-of-plane crystal orientations. These disparities result from differences in the dangling bonds associated with in-plane and out-of-plane crystal planes. Consequently, these variations affect the microscopic surface energy, influencing the migration and diffusion of molecules on the surface. Additionally, the unevenness of the heteroepitaxial surface physically increases resistance to molecular migration and diffusion, thereby reducing the diffusion length of the source atoms. These two factors collectively shape the molecular dynamics of nucleation at the interface, ultimately impacting the crystal quality of heteroepitaxial materials. Notably, the crystal quality of heteroepitaxial materials does not always correlate positively with the quality of the heteroepitaxial substrate.
