Abstract

Vanadium oxide catalysts doped or mixed with 1-50 mole % Fe<sup>3+ </sup>ions were prepared. The structure of the original samples and those calcined from 200 up to 500 °C were characterized by TG, DTA, IR and X-ray diffraction. The <i>S</i><sub>BET </sub>values and texture of the solid catalysts were investigated. The catalytic dehydration-dehydrogenation of isopropanol was carried out at 200 °C using a flow system. The results obtained showed an observable decrease in the activity of V<sub>2</sub>O<sub>5 </sub>on the addition of Fe<sup>3+ </sup>ions. Moreover, Fe<sub>2</sub>V<sub>4</sub>O<sub>13 </sub>is the more active and selective catalyst than FeVO<sub>4 </sub>spinels. The results were correlated with the active sites created on the catalyst surface.
