Abstract

The dependence of the O K L2,3 L2,3 and Na K L2,3 L2,3 Auger line intensities and the binding energy Eb of the O 1s photoelectron line of zeolites A, X, Y and mordenite on the structure induced charge transfer effects is demonstrated. Intensity of the O K L2,3 L2,3 Auger line and the Eb of the O 1s line are increased by shortening the T-O bond. Chemical shifts of the O 1s line are thus influenced predominantly by rehybridization of valence orbitals of the zeolites. Further experiments are need to explain the influence of structure-induced charge transfer effects on Auger line intensities and core level binding energies of ion-exchanged sodium in zeolites.
