Structural Evolution of Ag-LEV Zeolite upon Heating: an in situ Single-Crystal X-ray Diffraction (SC-XRD) and X-ray Absorption Spectroscopy (XAS) Study

Cametti, G.; Scheinost, A.; Churakov, S. V.

Abstract

Ag-modified zeolites are of great interest because of their improved catalytic, photocatalytic, sorption, and antibacterial properties []. To properly tune these properties, a deeper understanding of several structural factors is necessary. In particular, the following aspects have been proved to play a key role[]: i) the position of silver atoms with respect to the tetrahedral framework, ii) the possible formation of Ag-clusters within the zeolitic pores, and iii) the structural changes occurring upon dehydration, since most of these materials are employed after thermal treatment.
