Titel:
Unique Dynamic Changes of Fe Cationic Species under NH3-SCR Conditions 
Abstract:
The type and location of Fe cations in zeolite BEA and their structural changes under NH3-SCR conditions are reported, as they are important catalysts for the selective catalytic reduction of NOx with NH3. Adsorption of basic probe molecules such as NH3 and pyridine shows that additional Bronsted acid sites are formed at the expense of Lewis acidic octahedrally coordinated Fe cations during the aging cycle. The formation of new tetrahedrally coordinated Fe suggests that Fe cations are incorporat...    »
