Abstract
The adsorption of pyrrole over a series of Al203/MgO mixed oxides was studied by IR spectroscopy, since pyrrole could be a potential probe molecule for characterization of basic sites. The adsorption took place either via hydroxyl groups or via cations. The latter was followed by ring opening reactions or splitting off a proton from pyrrole. The feature determining interaction in all structures, was that of the nitrogen atom with an electronacceptor center of the surface. Therefore no estimations could be made about the base strength of the investigated oxides from these data.
