Description
| - Katalyzátory metatezí na bázi oxidu rhenistého naneseného na organizovanou mezoporézní aluminu (OMA) byly charakterizovány následujícími metodami: difrakcí rentgenového záření (XRD), rentgenovou fotoelektronovou spektroskopií (XPS), FTIR spektroskopií, MAS NMR spektroskopií a adsorpcí dusíku s cílem porozumět změnám texturních a chemických vlastností uvedených katalyzátorů, a to jak v procesu jejich aktivace tak v průběhu reakce metateze olefinů. Přítomnost pentakoordinovaného Al, četnost kyselých OH skupin, koncentrace Lewisových kyselých center a redukovatelnost Re 7+ na Re 4+ na povrchu OMA představují hlavní vlastnosti diskutované v souvislosti s katalytickou aktivitou.

- Metathesis catalysts based on Re(VII)oxide supported on organized mesoporous alumina (OMA) were characterized by a number of experimental techniques including X-ray diffraction (XRD), X-ray photoelectron (XPS) and FTIR spectroscopy, MAS NMR, and nitrogen isotherms to understand the changes in textural and chemical properties during the activation and the metathesis reaction of olefins. The presence of pentacoordinated Al, population of acidic OH groups, concentration of Lewis acid sites and reducibility of Re (VII) oxide to Re(IV) species in OMA based catalysts – there are the main features, which were discussed in connection with catalytic activity.
