For the first time a chemically consistent reaction cycle is suggested for the industrially important catalytic process of removing nitrogen oxide (NO) and nitrogen dioxide (NO2) from flue gasses by reduction with NH3. This process is known as selective catalytic reduction.

Associate Professor Susanne Mossin and PhD-student Anita Godiksen, both from DTU Chemistry, have just published the new reaction cycle in the journal ACS Catalysis. 

The reaction cycle has been investigated with state-of-the-art in-situ spectroscopy: Both EPR, IR and XAS have been used to follow the reaction and verify the individual oxidation and reduction steps.

The work has been done in collaboration with Haldor Topsøe A/S and the University of Turin, Italy.
