Abstract:	The activity and selectivity of Ni–V oxide catalysts in relation to the phase composition were investigated. The catalytic activity was measured in the oxidative dehydrogenation of methanol to formaldehyde and in the oxidation of SO₂ to SO₃.The oxide with the atom ratio $frac{V}{{V + Ni}} = 50%$ gives the highest yield of formaldehyde and the slowest rate of SO₂ oxidation. The above phase, as shown by X-ray and IR measurements, has a specific structure characterized by a weakened V=O double bond. Ni–V . SO₂ SO₃. $frac{V}{{V + Ni}} = 50%$ SO₂. , , , V=O
