摘要：

The oxidative coupling of methane (OCM) and the oxidative dehydrogenation of propane (ODHP) have been performed on new mixed Bi-V oxides having a gamma-Bi2MoO6-like structure. The results yield a correlation between the methane conversion and the oxygen diffusivity. The introduction of metals (Fe, Cu, Sr with 10 mol%) improves the C2 selectivity. The use of an oxide with a scheelite structure (BiVO4) shows that, under catalytic conditions, this oxide has the same behaviour as the above solids.
