Abstract
- The role of hydrogen in H2-assisted HC–SCR of NO x over Ag–Al2O3 is investigated by XPS and in situ DRIFT spectroscopy. Hydrogen does not reduce the surface silver species to metallic silver, however direct reduction of surface nitrates by hydrogen is observed. It is proposed that one important role of hydrogen is the removal of nitrates from the Ag–Al2O3 surface. [ABSTRACT FROM AUTHOR]
