Study of surface acid-base characteristics of aluminum hydroxide nanostructures

The paper studies the effect of electroexplosive Al/AlN powder oxidation conditions on surface acid-base characteristics of synthesized aluminum hydroxide nanostructures. Acid-base characteristics of samples are examined via the indicator method. It is demonstrated that the surface of synthesized nanostructures represents acid-base centers having different strength. Bronsted base centers with рK = 7.4, 9.2, 10.5 and 12.8 mainly prevail with a very small amount of Bronsted acid centers with рK=1.3, 3.46 and 5.2.
