The interaction between a γ-Al2O3 surface and vapors of H2O and D2O is studied via IR spectroscopy. It is shown that surface hydroxyl groups of ОН and OD form at temperatures as low as 100–200°С. It is estimated that these hydroxyl groups exhibit Brønsted acidity, and their interaction with NH3 leads to the formation of NH\(_{4}^{ + }\) ions.
