Abstract

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.
