Involvement of nitrate species in the SCR of NO by NH3 at ambient conditions over TS-1 catalysts
An IR and microcalorimetric study of adsorption and in situ reaction at room temperature of NO, O-2, NO2 and NH3 provides evidence of the involvement of surface nitrate species in this reaction. On the basis of this new experimental evidence a mechanism is proposed for the low temperature SCR reaction of NO by NH3 over titanium silicalites (TS-1).
