Tóm tắt

The comparative study of catalytic perfonnance of V(La)-containing TiO2 oxide in oxidative dehydrogenation of n-butanewas carried out. The aim of this work was to investigate effect of La adding on the propertiesof active sites and its impact on catalytic behavior in above mentioned reaction.is reported. Prepared catalysts were characterized byN2-adsorption for study of texture, H2-TPR and UV-vis spectroscopy for determination of vanadium complex speciation. Both prepared materials were tested in n-butane ODH reaction in the range of 400-550°C and obtained catalytic results were correlated with their structural and surface characteristics. The presence of La improves the catalyticactivity of V/TiO2.
