Abstract

original image

Die dreidimensionale Struktur von Silberionen enthaltendem Zeolith A wurde mit Röntgenbeugungsmethoden und Rastertransmissionselektronenmikroskopie untersucht. Trotz der Schwierigkeiten, die mit dem hohen Al-Gehalt von Zeolithen bei der mikroskopischen Untersuchung verbunden sind, konnte die Anordnung von einzelnen Ag-Ionen und Ag-Clustern, die aus sechs Atomen bestehen, visualisiert werden (siehe Bild).
