On. Sil'Chenkova et al., Intermediates determined by in situ IR-spectroscopy in low-temperature oxidation of ammonia on Fe2O3, KINET CATAL, 40(4), 1999, pp. 526-531
A spectrokinetic study of the reactivity of surface complexes in low-temper
ature ammonia oxidation over iron oxide was carried out. It was shown that
the surface complexes (NH3)(ads) and N2Oadsdelta- are the intermediates in
the process. Our data about the real intermediate complex suggest a stepwis
e mechanism of the process. Quantitative analysis shows that the use of thi
s mechanism gives a satisfactory description of the spectral and kinetic ch
aracteristics of the process on iron oxide.
