Description
  • It was confirmed, that the CO stretching frequencies in Li+-FER zeolite are site specific. This site specificity is driven mostly by the differences in Li+ coordination to zeolite framework. By comparison of relative intensities of individual carbonyl complex IR bands among samples with different amount of aluminium it was clear, that there are significant differences in amount of lithium ions in particular extraframework sites. This comparison suggests a supports, that there are some rules influencing the aluminium distribution in zeolite framework during the synthesis of each material. FTIR spectroscopy of Li+-carbonyls in zeolites may be used to investigate of this phenomenon.

  • Bylo potvrzeno, že vibrace CO v Li-FER zeolitu je specifická. Tato specificita je dána především rozdílem v koordinaci jednotlivých Li+ iontů k zeolitu. Porovnáním relativních intenzit jednotlivých IČ pásů přináležejících jednotlivým komplexům na materiálech lišících se koncentrací hliníku v mřížce byly objeveny výrazné rozdíly v distribuci jednotlivých komplexů. To znamená, že existují jistá pravidla pro distribuci hliníku v mřížce během syntézy zeolitu. Studium IČ spekter CO?Li komplexů může být použito k výzkumu tohoto jevu. (cs)
