The catalysts were characterized with respect to X-ray diffraction, BET surface area, temperature programmed oxidation, and temperature programmed desorption of ammonia. These catalysts have been evaluated for their activity for NO-CO reaction using a steady state gas laboratory evaluation assembly. The catalysts show high activity for NO reduction and almost 100 percent conversion of NO to N-2 was observed below 400 degrees C. The activity was found to be a factor of ruthenium content, however, Ru-mordenite in Na form was observed to be relatively more active than Ru-mordenite in H form, probably due to the electron donation from sodium to ruthenium sites.
