Abstract

Transition metal ion-exchanged zeolites offer outstanding catalytic properties due to their cations, representing one type of active center. Detection of their sites and accessibility to adsorbates are important goals of fundamental research. As extra-framework cations are indicated by translatory absorptions in the FIR, in-situ observation of their alterations upon admission of reactants should shed light on their role in catalysis. Copper-exchanged zeolite Y has proved to be highly active in butadiene cyclodimerization. This induced us to investigate this system in more detail.
