Abstract
Novel vanadium oxide based catalyst derived from the open-framework solid, [Co3V18O42(H2O)12(XO4)]·24 H2O (X = V, S) (1) catalyses oxidative dehydrogenation of propane to propylene. Catalyst activity was evaluated in the temperature range 250–400 °C with varying gas hourly space velocity (GHSV). At 350 °C and GHSV of 9786 h−1 and at 1.3% propane conversion the selectivity to propylene was 36.8%. The major products obtained were propylene and CO x (CO2 and CO). The ratio of the propylene to CO x depended directly on the catalytic sites present. Thus, as the amount of the catalyst was decreased, the conversion decreased with an increase in the propylene selectivity and a decrease in the selectivity to carbon oxides—CO x . The catalyst has been characterized by temperature programmed reduction and diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS).

Notes
While as prepared catalyst material is highly crystalline with a well-defined XRD pattern and resolved crystal structure, the catalyst loses its crystallinity upon heating as evidenced by the broad peaks in the X-ray powder diffraction patterns of the pretreated (at 350 and 450 °C) catalyst as well as the catalyst recovered after the catalyst testing experiments. Thus, DRIFTS provides an insight of structural changes in the catalyst framework following pretreatment and ODH catalysis experiments.
