Adsorption of NOx species on a-alumina and Ag/a-alumina has been investigated by in-situ DRIFTS and DFT calculations. The measured IR spectra show broad features, assigned to different NOx surface species and the calculations show that different Ag cluster sizes and different surface terminations influence the positions of the vibrational modes.
