On the role of strength and location of Brønsted acid sites for ethylamine synthesis on mordenite catalysts

Liquid phase synthesis of ethyl-tert-butyl ether: The relationship between acid, adsorption and catalytic properties of zeolite catalysts

“…The key characteristic of catalysts used in numerous processes, proceeding by acid-base mechanism, is their acidity distribution (the nature of acid centers, their concentration and acidity) [1][2][3][4][5][6][7].…”

Synthesis of single-site copper catalysts for methane partial oxidation

“…3c), in good agreement with previous reports. 19 Thus, it is concluded that independent of the location of the cations during ion exchange, in the final stage of dehydration and thermal activation Na + is competing with Cu 2+ for framework Al-O tetrahedra located in the side pockets. Therefore, we attribute the lower activity of CuNa-MOR compared to CuH-MOR to a competition of Na for those T-sites required to host the active Cu-oxo cluster.…”

Amination Reactions

“…The correct strength of acid sites is crucial for high activity and selectivity [35][36][37][38]. Ammonia and amines are assumed to adsorb on Brønsted acid sites and to form ammonium species.…”
