Catalytic Performances

Hydrophobic Sn-Beta zeolites, hydrothermally synthesized via structural reconstruction, exhibit unparalleled catalytic performances for Lewis acid-catalyzed reactions, far outperforming post-synthesized Sn-Beta and state-of-the-art Sn-Beta-F materials.

Beta Zeolites

Sn-Beta zeolites, with high Sn content and smaller crystal size, hydrothermally synthesized in F−-free medium using N-cyclohexyl-N,N-dimethylcyclohexanaminium hydroxide as the structure-directing agent with the assistance of Na+ and seed, are highly active as Lewis acid catalysts.
