TL;DR: The supported V2O5-WO3/TiO2 catalysts have become the most widely used industrial catalysts for selective catalytic reduction (SCR) applications since introduction of this technology in the early 1970s as mentioned in this paper.

TL;DR: The current study serves to resolve the long-standing controversy about the active sites for SCR of NO with NH3 by supported V2O5-WO3/TiO2 catalysts.

TL;DR: In this paper, a 2-site mechanism for selective catalytic reduction (SCR) of NOx with NH3 to N2 with supported V2 O5 (-WO3 )/TiO2 catalysts is investigated.

TL;DR: In this article, the SCR reaction occurs at surface V5+O4 sites that are maintained in the oxidized state by O2 and the rate-determining step involves the reduction of V5 + O4 sites by NO and NH3, specifically the breaking of N−H bonds during the course of formation or decomposition of the NO−NH3 intermediate.

TL;DR: In this article, a series of temperature-programmed surface reaction studies with isotopic labelled reactants was performed to elucidate the fundamental aspects of the N2O formation reaction and to guide the rational design of improved SCR catalysts for diesel engines with reduced NO produced.
