Evidence for an H2 promoting effect in the selective catalytic reduction of NO(x) by propene on Au/Al2O3.
Résumé
This work provides the first experimental evidence of an H2 effect in
C3H6-SCR over an Au/Al2O3 catalyst. This effect could only be
observed when the number of Au catalytic sites was decreased.
The N2 turnover rate estimated for the first time for the Au catalytic
sites for H2–C3H6-SCR was found to be similar to that estimated for
Ag ones supported on Al2O3.
