Infrared Spectroscopic Study of the Acidic Character of Modified Alumina Surfaces by Aline Auroux, Antonella Gervasini

“…It was found that, following treatment with lithium acetate or ammonium sulphate, the same –OH groups were involved in both modifications, acting in turn as acidic –OH groups capable of exchanging their protons with lithium ions or as basic groups capable of exchanging with acid sulphate anions or acting as strong nucleophiles to form hydrogen carbonates with carbon dioxide. Modified alumina experienced a general weakening of its initial Lewis acid centres on loading with Li + ions. …”
