A commercial zeolite-based catalyst for NOx removal via ammonia SCR was studied with
either pure NO or pure NO2 (as NOx compounds). The SCR efficiency was greatly …

NOX is a major atmospheric pollutant that is emanated by motor vehicles, thermal power
plants, and industrial boilers. Therefore, the removal of NOX is a research hotspot in the …

The selective catalytic reduction (SCR) of NO x with NH3 at high temperature (T> 500° C)
usually has low conversion efficiency due to the undesired NH3 over-oxidation. To suppress …

A commercial zeolite-based catalyst for NOx removal via ammonia SCR has been studied in
a synthetic flow very close to a real automotive exhaust mixture. Particular attention has …

The zeolite structure determines the product species, which is important for revealing the
hydrocarbons (HCs) deactivation mechanism and preventing HCs poisoning on Cu-based …

In this study Aluminium-free ZSM-5 type nanopowder ferrisilicates (as K–FZ or Na–FZ) were
synthesized successfully from silicic acid, potassium (or sodium) carbonate and iron (III) …

The present paper shows a direct comparison of IR spectra of adsorbed NO on two catalyst
systems (Fe-silicalite and Fe-ZSM-5), recorded in a flow-through cell (in operando, where …

This paper deals with the spectroscopic characterisation and catalytic activity of Fe-ZSM-5
samples prepared by aqueous exchange with ferric oxalate and Mohr salt as precursors …

The selective catalytic reduction (SCR) of NO was investigated by in situ diffuse reflectance
infrared spectroscopy (DRIFTS) over catalysts based on iron-pillared clays (Fe-PILC) ion …
