摘要
This work provides the first experimental evidence of an H-2 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 N-2 turnover rate estimated for the first time for the Au catalytic sites for H-2-C3H6-SCR was found to be similar to that estimated for Ag ones supported on Al2O3.
