Abstract

IR, ESR, and XRD studies of MoO₃MgF₂ samples revealed the existence of two types of complexes on the surface of the MgF₂ support, namely, isolated MoO₃ tetrahedra and clusters of MoO₆ octahedra of the MoO₃ structure. Changes in the degree of hydroxylation of the magnesium fluoride surface after impregnation with molybdate ions were followed by IR spectroscopy. Determination of acid-base properties by means of probe molecules such as pyridine and acetic acid enabled the origin of the acid centres to be explained. The appearance of new acid-base and redox centers in MoO₃MgF₂ samples is responsible for their activity in many catalytic reactions. © 1988.
