title: (15)N2 formation and fast oxygen isotope exchange during pulsed (15)N(18)O exposure of MnOx/CeO2.
abstract: Pulsing (15)N(18)O onto an annealed 1% Mn(16)Ox/Ce(16)O2 catalyst resulted in very fast oxygen isotope exchange and (15)N2 formation at 295 K. In the 1st (15)N(18)O pulse, due to the presence of large number of surface oxygen defects, extensive (15)N2(18)O and (15)N2 formations were observed. In subsequent pulses oxygen isotope exchange dominated as a result of highly labile oxygen in the oxide.
