Starting from the late seventies, the progressively increased availability of synchrotron light
sources allowed the execution of experiments requiring a high X-ray flux in a continuous …

An overview is given of the selective catalytic reduction of NOx by ammonia (NH3‐SCR)
over metal‐exchanged zeolites. The review gives a comprehensive overview of NH3‐SCR …

For the first time, the standard and fast selective catalytic reduction (SCR) of NO by NH3 are
described in a complete catalytic cycle that is able to produce the correct stoichiometry while …

The diesel oxidation catalyst (DOC) has been part of diesel exhaust systems since
regulations were introduced to limit the amount of harmful emissions released to the …

The deposition of WO x species using conventional impregnation method is a very simple
and efficient way to adjust the surface acidity and redox ability of hematite Fe 2 O 3 …

Cu-exchanged zeolites have demonstrated widespread use as catalyst materials in the
abatement of NO x, especially from mobile sources. Recent studies focusing on Cu …

Selective catalytic reduction of NOx using NH3 or hydrocarbons (NH3-SCR or HC-SCR) in
oxygen-rich exhaust from diesel engines remains a major challenge in environmental …

We present a systematic study of the chemical steps in the NO/NO2–NH3 fast SCR reaction
2NH3+ NO+ NO2→ 2N2+ 3H2O over a commercial Fe-ZSM5 catalyst. The study is based on …

The effect of Si content in SAPO-34 on NO selective catalytic reduction over Cu/SAPO-34
catalyst was investigated. Three fresh catalysts with different Si contents, prepared by the …

The NH3-SCR (selective catalytic reduction) reactions were systematically investigated over
a commercial copper zeolite catalyst in view of its application to the DeNOx aftertreatment of …
