A series of catalysts, NiSO4/Fe2O3 was prepared by the impregnation method using an aqueous solution of nickel sulfate. The addition of nickel sulfate to Fe2O3 shifted the phase transition of Fe2O3 from amorphous to hematite to higher temperatures because of the interaction between nickel sulfate and Fe2O3. The acidity and specific surface area of catalyst increased gradually in proportion to the NiSO4 content up to 20 wt%. Upon the addition of only small amount (3 wt%) of NiSO4 to Fe2O3, both the acidity and specific surface area increased remarkably, showing the presence of Bronsted and Lewis acid sites on the surface of NiSO4/Fe2O3, The optimum calcination temperature for the generation of strong acid sites through the reaction between NiSO4 and Fe2O3 was found to be 500 ℃. The catalytic activities for both reactions, 2-propanol dehydration and cumene dealkylation were correlated with the acidity of catalysts measured by the ammonia chemisorption method.
