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.
