MCM-41

[3] MCM-41 consists of a regular arrangement of cylindrical mesopores that form a one-dimensional pore system.

Contrary to zeolites, the framework of MCM-41 has no bronsted acid centers because there is no aluminium contained in the lattice.

[4] MCM-41 is not hydrothermally stable because of the slight wall thickness and the low degree of cross-linking of the silicate units.

[3] To achieve a defined pore diameter surfactants are used that form micelles in the synthesis solution.

The surfactant first forms rod-like micelles that subsequently align into hexagonal arrays.
