The IR spectra of the pyridine has been measured following adsorption on and subsequent desorption from Fe-montmorillonite (Fe-mont.). The exposure of strong Brønsted and Lewis acid sites on solid surfaces is a prime demand for potential adsorptive and catalytic applications. In situ IR spectroscopy of small adsorbed base molecules, often pyridine (Py), CO, NH 3 or NO molecules have been well...
