We report for the first time a comparison of molybdenum oxide species supported on three different industrially relevant mesoporous supports—Al2O3, SiO2 and TiO2 in ODH of n-butane. All samples were prepared by wet impregnation and characterized by ICP-EOS for determination of molybdenum content, XRD and N2-adsorption for study of morphology and texture, H2-TPR and DR UV-vis spectroscopy for determination of molybdenum complex speciation and by NH3-TPD for study of acidity. All prepared materials were tested in n-butane ODH reaction at 540°C and iso-conversion conditions. The molybdenum oxide supported on alumina exhibited the extraordinary high productivity (1.16kgprod kg cat −1 h−1) in ODH of n-butane which is one of the five highest C4-deh productivity values which were published for ODH of n-butane in open literature. Moreover, this catalyst exhibit high selectivity to 1,3-butadine in comparison with other catalysts tested in n-butane ODH.
