Abstract
The sorption of methanol on MCM-22 and MCM-36 materials was studied using mainly IR spectroscopy. MCM-36 materials pillared with (mixed) oxides such as SiO2, Al2O3, MgO-Al2O3, and MgO-Al2O3-SiO2, exhibit widely varying acid-base properties. Methanol is associatively adsorbed on Brønsted acid sites in the zeolitic micropores and associatively and dissociatively on acid and base sites in the mesopores. Lewis acid/base sites are responsible for dissociative adsorption. Stable formates were only formed upon heating MgO-Al2O3-MCM-36 saturated with methanol.
