Highly porous aluminum oxide ceramics were synthesized by various low energy consumption techniques. This work demonstrates the efficiency of the preparation technique to tailor the structure of the materials. The drying method was varied and applied in vacuum (freeze drying), under supercritical conditions, and at atmospheric pressure. The pore system and the absorbability can be significantly affected by the conditions of the drying process. The absorbability of porous materials was compared basically for organic compounds. The gas and liquid adsorption measurements were carried out on a gas chromatography and mass spectrometry instrument. The absorbability of several porous aluminum oxide materials was compared to the adsorption data of pure carbon.
