“…Mordenite (MOR) is commonly known as largepore zeolite with unique properties of the structure as it possesses a 12-member ring main channel (0.7 × 0.65 nm) and 8-member ring small channel (0.57 × 0.26 nm) oriented along the c-axis and interconnected by 8-member ring side pockets (0.34 × 0.48 nm) [20,21]. In general, the catalytic properties of MOR are primarily determined by its framework's topologies and composition [22].…”

Since the discovery of the Methanol-to-Olefins (MTO) process as a sustainable and nonpetroleum method for generating light olefins, there has been a growing interest in the utilization of acidic zeolite catalysts. In this review, we highlighted the application and modification of MCM-22 and MOR zeolite catalysts, shedding light on their distinctive properties and the ongoing endeavors to optimize their catalytic performance. Notably, the choice of catalyst and specific modifications significantly influence the outcomes of light olefin selectivity, propylene-to-ethylene (P/E) ratios, and catalytic lifetime. This research offers insights into the current status of research on MCM-22 and MOR zeolites and imparts a valuable understanding of the developments of both catalysts in this crucial catalytic field.

Nanocrystalline mordenite (MOR) zeolites were hydrothermally synthesized in a single step with commercial cetyltrimethylammonium (CTA) hydroxide as the sole organic template, while the aluminum source was varied in a typical synthesis gel. CTA can effectively reduce the crystal growth of MOR zeolites, in some cases selectively in the a‐ and b‐directions of the unit cell. These nanocrystalline MOR zeolites do not only have a larger external surface area than their bulk counterparts prepared without CTA, but the Brønsted acid sites in the side‐pockets are also more accessible. The combination of the use of CTA and AlCl3 ⋅ 6H2O afforded the best‐performing catalyst with much improved activity in benzene alkylation and hydroconversion of n‐hexadecane (n‐C16). Modifying MOR synthesis with CTA hydroxide is a cheap and effective method to open up the one‐dimensional micropore system of mordenite, increasing the catalytic performance in hydrocarbon reactions.
