Remarkable structure(NO_x-TPD)-activity(C₃H₆-SCR) correlations allowed us to unravel the reason for the existence of an optimum Ag loading for Ag/Al₂O₃ catalysts in the C₃H₆-SCR of NO_x. The so-called optimum loading of about 2wt% Ag on Al₂O₃ corresponds to the maximum loading of Ag for which maximum dispersion of Ag is preserved.
