The invention relates to the catalytic activity and selectivity of microporous, amorphous glasses of mixed metal oxides and the application thereof in the form of shape selective, heterogeneous catalysts. Microporous, amorphous mixed metal oxides (glasses) can be formed by polycondensation of soluble metal compounds. These new materials show a temperature stability up to 800.degree. C. These amorphous glasses shown in heterocatalytic reactions selective oxidation, hydrogenation, hydrocracking and condensation catalysis.
