Aluminum oxide (Al2O3, CAS number 1344-28-1) nanopowder, known as alumina, is one of the most frequent metal oxides used in industry due to its abundance in nature and low-cost production. Alpha (α), Beta (β) and gamma (ƴ) are the most well-known phase modifications of aluminum oxide. On the nanoscale, gamma alumina is the most stable phase with high surface area and thermal stability. γ-Al2O3 nanopowder has unique properties including amphoterism, high catalytic activity, high melting point and high hardness.
γ-Al2O3 is used as a carrier of catalysts and a desiccant in processes of chemical and petrochemical production owing to its high surface area with open porosity and relatively stable over the temperature range of interest for most catalytic reactions. Aluminum oxide nanoparticles can also serve as additives to concrete mixtures, cosmetics, and textile industries. Aluminum oxide nanoparticles have also been used as antibacterial agent for biomedical purposes. Owing to its electrical resistance, aluminum oxide scaffold is beneficial for suppressing charge recombination, preventing moisture penetration, and increasing the thickness of light absorber layer in perovskite solar cells.
