Methane oxidation on vanadium oxide catalysts synthesized by molecular dispersion on aerosil

It has been found that (≡Si−O)2V2xO5x−1 catalysts accelerate partial and complete oxidation of CH4 at 450–550°C. The steps responsible for the rate of the overall reaction with the participation of N2O at low temperatures involve single V-centers and\(\mathop {O^ - }\limits^. \), whereas in the oxidation by O2 at higher temperatures V-“clusters” and O2−-species take part.
