Catalytic Conversion of Methane into Oxygenated Compounds over H4PMo10WVO40 Catalyst

The partial oxidation of methane into oxygenated compounds over H₄PMo₁₀WVO₄₀ catalyst was investigated at different reaction temperatures and the catalytic activity was examined. The products obtained were methanol, formaldehyde and carbon oxides. The results obtained have shown that IR, UV, NMR spectroscopy and X-ray diffraction indicate for H₄PMo₁₀WVO₄₀, the presence of a single crystalline phase and IR spectra typical of the Keggin anion. After reaction H₄PMo₁₀WVO₄₀ were decomposed into P₂O₅, V₂O₅, MoO₃ and WO₃.
