dc.description.abstractThe incorporation of platinum into the cavities of NaX zeolite was realized by impregnation and thermal decomposition of the organometallic compound Pt(II)-acetylacetonate dissolved in acetone. A high dispersion of platinum to predominantly mono-atomic particles was achieved thanks to the tight fit of the Pt(II)-acetylacetonate molecules in the aperture of the zeolite supercage. Using the high angle annular dark field imaging technique of HRTEM, individual Pt particles situated within the zeolite crystals were, for the first time, clearly visible. This offers new possibilities of studying the distribution of incorporated metal particles along the crystal depth.en
dc.description.abstractPlatina je ugrađena u kaveze zeolita NaX impregnacijom i termalnim razlaganjem organometalnog jedinjenja Pt(II)-acetilacetonata, rastvrenog u acetonu. Visoka disperznost platine pretežno u vidu jednoatomnih čestica, postignuta je zahvaljujući bliskosti dimenzija molekule Pt(II)-acetilacetonata i prečnika ulaznog otvora supekaveza zeolita. Tehnikom širokougaone difrakcije i tamnog polja ultravisokorezolutivne elektronske mikroskopije, prvi put su učinjene vidljivim individualne čestice platine smeštene unutar kristala zeolita, što otvara nove mogućnosti u proučavanju raspodele ugrađenih metalnih čestica po dubini kristala.sr
