A Study of Propane and Propene Ammoxidation over Antimony-Vanadium-Oxide Catalysts at Steady-State and Transient Conditions
Propane ammoxidation catalysts of differing Sb/V ratio and consisting of differing amounts of the V2O5, alpha-Sb2O4, and Sb0.92V0.92O4 phases were prepared. In the first paper, the structure of Sb0.92V0.92O4 was determined by thermogravimetry, X-ray microanalysis, X-ray powder diffraction, and neutron powder diffraction. Sb0.92V0.92O4 was found to have a defective rutile structure involving catio
