Bimetallic molybdenum-containing oxides have a wide range of applications including numerous catalytic reactions. Previous work has shown that the preparation method has a marked influence on the physical and chemical properties of these kinds of metal oxides. Accordingly, a facile, low-temperature synthetic approach for the preparation of molybdenum-containing bimetallic oxide catalysts with controlled shape and chemical composition via the pyrolysis of water-based bimetallic single-source precursors will be reported. The precursors result from the reaction of aqueous solutions of alkaline earth metals or divalent first row transition metal salts of 2-hydroxycarboxylic acids (eg. lactic acid, 2-methyllactic acid, mandelic acid, and benzilic acid) with solid MoO3. They crystalize with the exact ratio of divalent metal to molybdenum for formation of MMoO4. TGA and XRD analysis has shown that the thermal decomposition of these single source bimetallic precursors produces the target materials. Several potential catalytic reactions will be discussed including oxidative dehydrogenation and production of petrochemicals via pyrolysis of biomass.
