Abstract
Pulsing (15)N(18)Oonto an annealed 1% (MnOx)-O-16/(CeO2)-O-16 catalyst resulted in very fast oxygen isotope exchange and N-15(2) formation at 295 K. In the 1st (NO)-N-15-O-18 pulse, due to the presence of large number of surface oxygen defects, extensive (N2O)-N-15-O-18 and N-15(2) formations were observed. In subsequent pulses oxygen isotope exchange dominated as a result of highly labile oxygen in the oxide.
