Conclusions

  1. 1.

    The method of photoelectron spectroscopy has been used to show that the Co and Mo ions of CoO-MoO3-Al2O3 catalysts interact with the γ-Al2O3 lattice, the Mo ions blocking the penetration of the Co ions. Formation of metallic Co promotes extensive Mo ion reduction.

  2. 2.

    Thermal treatment of the CoO-MoO3-Al2O3 catalyst in air tends to enrich the surface with respect to Mo ions, while reduction enriches the surface with respect to Co ions.

  3. 3.

    Oxidational treatment of the CoO-MoO3-Al2O3 and MoO3-Al2O3 catalysts is required for formation of anthracene radical-cations. A description is given of an oxidizing center structure which accounts for the reduction in acceptor activity of the Mo6+ ions in the ternary system.
