Реферат: The active oxidation state of Mo in the aromatization of n-hexane over MoO3/Al2O3 was identified by XPS and pulse catalytic investigations. By application of a novel approach to the interpretation of the Mo 3d spectra of reduced supported Mo catalysts (linear relation between binding energies and oxidation states) it was shown that Mo(II) is formed during the reduction of MoO3/Al2O3. Mo(II) was identified as the active Mo state in the aromatization reaction by a correlation between the initial activity of reduced MoO3/Al2O3 catalysts (reaction temperature 723 K) and the amount of Mo(II) in them. The product distribution in the cracking reaction that accompanies the aromatization is proposed as a chemical probe for the presence of Mo(0).
