Abstract: It was found that the surface of single-phase aluminum oxides contains terminal, bridging, and hydrogen-bonded hydroxyl groups, which differ in both concentration and position of related absorption bands. A transition from η-Al2O3 to θ-Al2O3 does not change the number of absorption bands, but the intensities of these bands decrease. The total concentration of Lewis acid sites in single-phase oxides increases from 2.5 to 5.34 µmol/m2 for γ-Al2O3 and θ-Al2O3, respectively. As distinct from other species, η-Al2O3 contains strong Lewis acid sites (ν(CO) = 2238 cm−1). The total concentration of basic sites in aluminum oxides prepared by boehmite dehydration at 600, 800, and 1000°C decreases from 4.86 to 3.72 µmol/m2.
