Aromatic compounds‐mediated synthesis of anatase‐free hierarchical TS‐1 zeolite: Exploring design strategies via machine learning and enhanced catalytic performance

Simultaneous achievement of constructing mesopores and eliminating anatase is a long-term pursuit for enhancing the catalytic performance TS-1. Here, we developed an aromatic compounds-mediated synthesis method to prepare anatase-free hierarchical TS-1 olefin epoxidation. A series zeolites were prepared by introducing compounds containing different functional groups via crystallization process. The formation intercrystalline insertion titanium into framework facilitated at extent. synergistic coordination carboxyl hydroxyl in with Ti(OH)4 realizes uniform distribution species eliminates generation anatase. Noteworthily, eight machine learning models trained reveal mechanism additive preparation conditions on microstructure optimization. prediction accuracy most can reach more than 80%. Benefiting from larger mesopore volumes (0.37 cm3·g−1) higher content Ti species, TS-DHBDC-48h samples exhibit other zeolites, giving 1-hexene conversion 49.3% 1,2-epoxyhenane selectivity 99.9%. paper provides facile strategy promotes application toward design optimization new zeolites.
