Ferrierite based catalyst is expected to be used for high-temperature decomposition of N2O. The stability of the ferrierite structure and divalent cations in ferrierite in this process were analysed using XRD, SEM, FTIR, 27Al and 29 Si MAS NMR. This

The long-term stabilities of a group of iron zeolites with MFI, *BEA, and FER structures and similar Fe/Al ratios were evaluated to assess their performance as catalysts for N2O decomposition. Conditions relevant for the application of the catalyst a

The role of NO in the N2O decomposition under conditions relevant to its formation by NH3 oxidation during nitric acid production over iron-containing ferrierite (Fe-FER) catalyst was investigated. In particular, the relative productions of O2 and NO

The scope of the study was to identify the performance and long-term stability of Fe-FER for N 2 O decomposition under conditions relevant for use as a secondary-level catalyst for N 2 O decomposition in the production of HNO 3 , i.e., in a complex g

The high-temperature decomposition of N2O in a structured catalyst was studied using a full three-dimensional (3D) model in the temperature range 700–900 °C and high pressure (0.4–0.8 MPa), under realistic gas phase composition, i.e. with 1000 p
Reduction of NO by NH3 over metal-promoted zeolites represents the principal reaction in the selective catalytic reduction (SCR) technology for NOx removal from Diesel engine exhausts. It has been established that addition of ammonium nitrate (AN) to

Much research has been published on the isomerization of C5–C7 paraffins using Pt/WO3–ZrO2 (PtWZr) catalysts. However, to our knowledge, most of these researchers only used model feedstocks. Therefore, we tested the activity of a Pt/WO3–ZrO2 ca

The heterogeneity and redox behavior of Fe-cationic species in Fe-ZSM-5 catalysts for N 2 O decomposition and NH 3 -SCR-NO x were analyzed by Mossbauer and UV–Vis spectroscopy, TPR-H 2 , and reaction kinetic measurements. Iron was introduced into Z

The structure and population of ion-exchanged Fe ions, Fe-oxo species, and Fe-oxo oligomers and Fe2O3 oxide particles and the concentration of acid sites in non-steamed and steamed Fe-ZSM-5 were elucidated using semi-quantitative Mossbauer and FTIR a

Presence of metallic Pt clusters highly enhances catalytic activity of iron ferrierite in N 2 O decomposition, even at low Pt loading (Pt/Al > 0.003). Platinum (II) cations in ferrierite are inactive; only some low activity appears with pre-reduced s
