摘要

Pulsing ~(15)N~(18)O onto an annealed 1% Mn~(16)O_x/Ce~(16)O_2 catalyst resulted in very fast oxygen isotope exchange and ~(15)N_2 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)N_2~(18)O and ~(15)N_2 formations were observed. In subsequent pulses oxygen isotope exchange dominated as a result of highly labile oxygen in the oxide.
