I comment on the XPS analysis of these catalysts as a function of MnOx–CeOx content. I argue that it is the total number of oxide sites that enhances the catalysts’ de-nitrification power, and not the MnOx–CeOx interaction, as the authors hold.

Activated Coke

On the modified activated coke, the CeOx species, promoting NOx adsorption, significantly increased the starting denitrification activity and the Mn species, helping NH3 adsorption, showed a gradual increase in activity after a time delay.
