Abstract
Adsorption of various molecular probes on MgAlPO4-5 and CoAlPO4-5 is s tudied by diffuse-reflectance IR spectroscopy. It is shown that proton -donor centers are present in the structure of these aluminophosphates , and their acidity is estimated. A modifying effect of the introduced metal ions on the adsorption properties of the aluminophosphate frame work is revealed.
