Abstract

<p>Catalysts containing 20 wt.% Co<sub>3</sub>O<sub>4</sub> supported on γ-Al<sub>2</sub>O<sub>3</sub> and MgO were prepared. The catalyst precursors were analyzed by TG, DTG and DTA, and the calcined catalysts (400-700 °C) were characterized by XRD. The amount of excess surface oxygen for the catalysts was estimated iodometrically. The vapour-phase decomposition of isopropyl alcohol over these catalysts was studied. Co<sub>3</sub>O<sub>4</sub>/γ-Al<sub>2</sub>O<sub>3</sub> catalysts are selective towards propene formation, whereas Co<sub>3</sub>O<sub>4</sub>/MgO catalysts are selective towards acetone formation. The poisoning effect of Co<sub>3</sub>O<sub>4</sub> on both supports and the activity of the catalysts is discussed.
