“…A recent study of bimetallic catalysts [31] shows that the order of metal introduction can be a factor affecting their catalytic properties. Thus, the order of component deposition in binary materials has been proposed as a parameter to improve the catalytic activity and modify the properties [32][33][34][35]. Moreover, particular attention has been paid to the study of certain parameters in catalysts for the process of catalytic reduction of NO x , such as the metal exchange degree [14,36], the framework type [37], the Si/Al ratio [38][39][40], the cationic chemical composition [41,42] and the reaction conditions.…”

Mono- and bimetallic systems of Ag, Fe, and Ag–Fe exchanged in sodium mordenite zeolite were studied in the reaction of NO reduction. The transition metal cations Ag and Fe were introduced by ion exchange method both at room temperature and 60 °C; modifying the order of component deposition in bimetallic systems. These materials were characterized by Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES), ultraviolet-visible spectroscopy (UV-Vis), X-Ray photoelectron Spectroscopy (XPS) and High-resolution transmission electron microscopy (HR-TEM). The XPS and UV–Vis spectra of bimetallic samples revealed that under certain preparation conditions Ag+ is reduced with the participation of the Fe2+/Fe3+ ions transition and is present in the form of a Ag reduced state in different proportions of Agm clusters and Ag0 NPs, influenced by the cation deposition order. The catalytic results in the NO reduction reaction using C3H6/CO under an oxidizing atmosphere show also that the order of exchange of Ag and Fe cations in mordenite has a strong effect on catalytic active sites for the reduction of NO.

“…These fluctuations lead to a special energy spread contribution (''structure induced energy spread") [20], which is often more significant than the ''classical" energy spread contributions of a stratified sample. This code is successfully used to determine the characteristics of the 3D sample structure analyzing RBS spectra taken on columnar-type porous silicon samples [21], fragmented silver surfaces [22] or silica nanoparticles [23].…”
