Shows efficient base and acid catalysis in mesoporous MCM-41, suggesting its potential in organic reactions.

The aim is to evaluate the catalytic properties of alkali-exchanged MCM-41 in various organic reactions.
Sodium and caesium cation-exchanged MCM-41 were synthesized and characterized.
Catalytic activities were tested in Knoevenagel condensation, acetalization, and aldol condensation.
Caesium acetate-impregnated MCM-41 was specifically examined for its base catalytic activity in the Michael addition.
Caesium acetate-impregnated MCM-41 exhibited strong base activity in the Michael addition.
Sodium and caesium exchanged MCM-41 acted as mild, selective, and recyclable catalysts for several reactions.
All catalysts showed stability in aqueous conditions.

Kloetstra et al. (1995) studied this question.
