The selective catalytic reduction (SCR) of NOx with NH3 to N2 with supported V2O5(‐WO3)/TiO2 catalysts is an industrial technology used to mitigate toxic emissions. Long‐standing uncertainties in the molecular structures of surface vanadia are clarified, whereby progressive addition of vanadia to TiO2 forms oligomeric vanadia structures and reveals a proportional relationship of SCR reaction rate...
Die Minderung von NOx‐Emissionen durch selektive katalytische Reduktion (SCR) auf Vanadiumoxid‐basierten Heterogenkatalysatoren wird durch Wolframoxid gefördert. In ihrem Forschungsartikel auf S. 12739 zeigen J. Z. Hu, Y. Wang, I. E. Wachs und Mitarbeiter, dass diese SCR über einen Zwei‐Zentren‐Mechanismus an benachbarten Vanadiumoxidzentren verläuft. Das Wolframoxid bewirkt die Oligomerisierung des...
