The Role of Silver for the H-2-Effect in H-2-Assisted Selective Catalytic Reduction of NOx with NH3 Over Ag/Al2O3
Artikel i vetenskaplig tidskrift, 2013

Silver/alumina catalysts are known to be highly active for hydrogen-assisted selective catalytic reduction (SCR) of nitrogen oxides. A comparison of silver/alumina and pure alumina catalysts shows that hydrogen conversion occurs on the silver. Subsequently formed NO2 is crucial for NH3-SCR and in addition products from the hydrogen conversion influence nitrates on the alumina by spill-over.
