Abstract
Surface basicity of alumina and modified alumina has been studied by FT-IR spectroscopy using boric acid trimethyl ester (BATE) as the probe molecule. The surface basic sites on alumina can be probed by the adsorption of BATE and coadsorption of BATE and CO2. BATE is found to interact with both types of basic sites on alumina: basic hydroxyls and surface oxygen anions. A general interaction model of BATE with basic sites on metal oxide is proposed.
