    MoVW-mixed oxide as a partial oxidation catalyst for methanol to formaldehyde
    (2006) Ramachandra, B.; Jung, S.C.; Kim, K.-S.; Choo, K.-Y.; Sung, J.-S.; Kim, T.-H.
    Mixed oxide with composition Mo0.65V0.25W 0.10Ox was synthesized and its catalytic activity for the selective oxidation of methanol to formaldehyde was investigated. The characterization by scanning electron microscopy, X-ray diffraction, energy dispersive X-ray and Fourier transform infra-red spectroscopy reveals that the prepared catalyst is inhomogeneous nanocrystalline Mo5O 14-type oxide with minor amount of MoO3-type and MoO 2-type material. Thermal activation treatment of the catalyst at 813K resulted in better crystalline sample. The overall structural analysis suggests that the catalytic performance of the MoVW-mixed oxide catalyst in partial oxidation of methanol is related to the formation of the Mo5O 14-type material. � 2006 Elsevier B.V.
