Abstract

Titanium-doped γ-Fe₂O₃ has been prepared by the calcination of a solid formed by the addition of aqueous ammonia to an aqueous solution of titanium- and iron-containing salts and boiling the precipitate under reflux. As compared to pure γ-Fe₂O₃ made by similar methods, titanium-doped gamma-Fe2O3 showed a higher surface area and a greater stability to reduction, thermal conversion to an α-Fe₂O₃-related structure and the maintenance of a higher surface area during oxidation-reduction cycling.
