Distinguishing the Silanol Groups in the Mesoporous Molecular Sieve MCM-41

摘要

The successful synthesis of M41S materia's a new family of novel silicates with uniform mesopores. opened a vast range of applications in catalysis, sorption, molecular recognition, electronics, and photochemistry. One of the members of this family ofmaterials is MCM-41. which contains a hexagonal array of mesopores with a pore diameter of 20-100 A depending on the conditions of its synthesis. It is postulated that the inorganic walls around the mesopo'es of MCM-41 are constructed of disordered SiO_4 tetrahedra! units, as is also the case for amorphous silicates.
