Tailored approach for hierarchization of all-silica zeolites

[EN] Adding secondary mesoporosity to all-silica zeolites can improve mass transfer, potentially leading to new applications in catalysis and separation. The tailored post-synthesis methods involving detemplation, desilication, and application of pore-directing agents were applied to examine the inf...

The tailored post-synthesis methods involving detemplation, desilication, and application of pore-directing agents were applied to examine the influence of zeolite type structure, crystal properties, and synthesis conditions on the hierarchization feasibility of all-silica ITQ-29 (LTA), silicalite-1 (MFI), silicalite-2 (MEL), and beta (*BEA) zeolites.
