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.

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.
