dcterms:description
The catalytic properties of various Pt-modified molecular sieves were tested in liquid-phase hydrogenation of cinnamaldehyde and compared to Pt/MgO and commercial Pt/C catalysts. The type of support considerably influenced the catalytic properties. The superior selectivity performance of microporous catalysts was confirmed; the highest selectivity to allyl alcohol of about 40% was obtained over the beta support whereas the mesoporous MCM-41-supported catalyst was unselective. The highest activity was obtained over the Pt/mordenite catalyst. In order to clarify the performance of catalysts, several characterization methods (XRD, XRF, FTIR, surface measurements) were employed.

Výběr nosiče – molekulárního síta významně ovlivňuje katalytické vlastnosti významně ovlivňuje katalytické vlastnosti použitých katalyzátorů. Pro charakterizaci katalyzátorů byla použita řada fyzikálně-chemických metod (RTG, XRF, FTIR a elektrochemická metoda pro měření povrchu Pt).
