The γ-Al2O3 nanosolids, a kind of porous activated alumina, are widely used in plastic, rubber, ceramic and fireproofing materials as the reinforcing agent, where its characteristic high thermal stability, adhesion resistance, high mechanical strength and wear resistance are required. It can also be uniformly dispersed in many solvents, for example water, ethanol, acetone, benzene and xylene. In this paper a novel method is applied to prepare porous γ-Al2O3 nanoparticles. This method, which combines mechano-chemical and sonochemical reactions, is extremely innovative and may inspire new ideas for preparation of nanomaterials.
