1.The introduction of bismuth into Fe-Co-Mo catalysts affects the degree of local lattice distortion in the neighborhood of the Fe3+ ions.2.Formation of a metastable ß-FeMoO4 phase results from thermal vacuum activation of Co-Mo-Bi-Fe catalysts, and from the interaction of such catalysts with propylene.3.The necessary and sufficient condition for the formation of ß-FeMoO4 is the generation of a critical concentration of point defects (anion vacancies) in the neighborhood of the ß-CoMoO4 interface. |
