| Izvleček: | In this research species of gold and iron in mixed Au/Fe/zeolite along with reference Au/zeolite and Fe/zeolite samples were studied. It was shown that calcinations temperature, type and cation of zeolite can significantly influence the iron and gold species. It was revealed that gold precursor is decomposed before temperature treatments with formation of reduced gold species in case of Au/zeolites. Reducibility of iron cations is higher for Fe-Y zeolites then for Fe-mordenites probably due to difference in their pore geometry. The addition of gold to iron-containing samples leads to modification of iron state in for Y- supported and NH4-mordenite samples. В фонде НТБ ТПУ отсутствует |
