| Description
| - Zeolity jsou krystalické mikroporézní materiály široce používané jako molekulární síta a katalyzátory v průmyslových chemických procesech. Zejména křemíkem bohaté zeolity (Si/Al>12) jako ZSM-5 (MFI skelet) přitáhly pozornost. Katalyticky aktivní species, to jest protony, kationty kovů a kov-oxid kovu kationty kompenzují negativní náboj mikroporézního hliníko-křemíkového skeletu [Sin-mAlmO2n]m- které jsou tvořené rohy sdílejícími TO4 tetrahedry (T=Si, Al-). Typickým rysem mnoha křemíkem bohatých zeolitů je vysoký počet krystalograficky rozlišitelných T posicí. Neboť kationické species se vážou k AlO4- tetraedrům, krystalografická posice hliníku v zeolitickém skeletu určuje lokalizaci aktivních species. (cs)
- eolites are crystalline microporous aluminosilicates widely used as molecular sieves and catalysts in industrial chemical processes. Silicon-rich zeolites (Si/Al>12) such as ZSM-5 (MFI framework) have found particular attention. The catalytically active species, that is, protons, metal cations, and metal-oxo cations, compensate the negative charge of the microporous aluminosilicate frameworks [Sin-mAlmO2n]m- made of corner-sharing TO4 tetrahedra (T=Si, Al-). A typical feature of many silicon-rich zeolites is a high number of crystallographically distinguishable T sites. Since the cationic species bind to the AlO4- tetrahedra, the crystallographic position of aluminum in zeolite frameworks governs the location of the active sites, which in turn affects the catalytic activity and selectivity.
