Popis: The morphology of zeolites influences their catalytic activity, but defining descriptors to link morphology and activity is challenging. Here, time-resolved in situ FT-IR spectroscopy and MD simulations reveal that the difference in the catalytic performance of a series of H-ZSM-5 zeolites with similar sheet-like morphology can be attributed to intracrystalline diffusive propensities in different channels.
