摘要： The present invention relates to doped or undoped aluminas having after calcination at 1200 °C for 5-24 hours a pore volume ≥ 0.5 ml/g and a BET surface area greater than 35 m2/g. The invention also relates to a method for preparing these aluminas comprising the steps of: a. preparing an aqueous solution of an aluminium salt with optional co-dopants, b. treating the aqueous solution with hydrogen peroxide, c. precipitating the alumina using a base, and d. filtering, drying and calcining the alumina.
