    Hydrogen-transfer dehydration between alcohols over V 2 O 3 and MoO 2 catalysts for the formation of corresponding alkanes and aldehydes
    摘要:
    Conversion of alcohols in a gas phase under N-2 flow at 573 K was carried out using V2O3 and MoO2 oxides with low valence oxidation states. It was found in the reaction of ethanol that equimolar amounts of ethane and acetaldehyde were catalytically formed as the main products over the oxides. Bi-products were small amounts of ethene and C4 compounds. Reactions of other alcohols (methanol, 1-propanol and 2-propanol) over the V2O3 and MoO2 catalysts also led to the equimolar formation of corresponding alkanes and aldehydes or ketone. It was confirmed by XRD and XPS that the low valence states of V2O3 and MoO2 were unchanged during the reactions and the oxides stably worked as the catalyst. Based on catalytic reaction results obtained under various reaction conditions (reaction temperature, contact time, introduction of H-2 and C2H4 into reaction stream) and on experiments of kinetic isotope effects on the ethanol reaction, a reaction scheme is proposed, in which hydrogen transfer reaction between two alcohol molecules adsorbed on metal-O2--metal sites on the surface of V2O3 and MoO2 catalysts takes place via 6-membered transition state, followed by dehydration.

  • Bismuth molybdates prepared by solution combustion synthesis for the partial oxidation of propene

    synthesis of mixed oxides with thermally sensitive metals, still keeping a good control on their stoichiometry and phase composition. Bismuth molybdates with different theoretical Bi/Mo atomic ratios, namely α-Bi2Mo3O12, β-Bi2Mo2O9, and γ-Bi2MoO6 were synthesized by the SCS, fully characterized by XRD, Raman, SEM/EDX, BET and XPS analyses, and tested in the partial oxidation of propene to acrolein.
