Abstract
The formation and adsorption of enolic species on a palladium promoted Ag/Al 2O 3 catalyst (denoted Ag-Pd/Al 2O 3) during the selective catalytic reduction (SCR) of NO x by C 3H 6 has been studied by means of DRIFTS and density functional calculations. The structure of the enolic species adsorbed on Ag-Pd/Al 2O 3 catalyst has been established based on the in situ DRIFTS spectra and simulated results. The reaction mechanism from C 3H 6 to enolic species on Ag-Pd/Al 2O 3 catalyst was proposed and the hypothesis about the Pd promotion was discussed.
