Role of Nitrate Species in the "NO2-SCR" Mechanism over a Commercial Fe-zeolite Catalyst for SCR Mobile Applications
The NO2-SCR reaction is studied by transient reaction analysis over a Fe-zeolite commercial catalyst. It is proposed that the NO2-SCR reaction occurs according to a mechanism wherein surface nitrates are first formed by NO2 disproportionation, followed by their catalytic reduction to nitrogen by ammonia.
