Abstract

Positron annihilation and Mossbauer-effect measurements were performed on fajausite X-, Y- and ZSM-5 zeolites in as-produced and also in ion-exchanged (with Fe and Pd or Pt) and subsequently reduced states. A correlation of the positron data with the filling-up of the cages of the zeolites due to the formation of metallic particles was found. The Mossbauer results revealed that the metallic particles are bimetallic.
