Popis: Thermal treatment and subsequent ammonolysis of MoO3/H-ZSM-5 is shown to be an effective means for the preparation of zeolite dispersed nitrided molybdenum species. However, it is unlikely that these species reflect the bulk structures formed by analogous treatment of bulk MoO3 precursor. The inclusion of low levels of Fe as a dopant does not produce any apparent effects on the Mo XPS spectra, although the amount of N incorporation is increased, and iron is shown to be reduced to Fe0. FTIR studies evidence the migration of molybdenum oxo species into the zeolite at the temperatures employed.
