Popis: A solid-state procedure has been developed which enables A13+ and Fe3+ ion-exchanged montmorillonite to be prepared via co-grinding of the clay with the appropriate metal nitrate at room temperature. Pyridine adsorption/infrared spectroscopic studies indicate that montmorillonite treated in this manner contains Bronsted and Lewis acid sites in significant quantities, suggesting that these easily prepared materials may be of interest as acid catalysts.
