摘要

RECENTLY a new family of mesoporous molecular sieves, M41S, was reported by researchers at Mobil R&D Corporation. As a member of the family, MCM-41, which exhibits a hexagonal array of uniform channel mesopores, has been synthesized. The channel sizecan be varied from approximately 1.5 nm to greater than 10 nm by choosing different surfactants, auxiliary chemicals (1, 3, 5-trimethylbenzene) in the reactant, and by changing the reaction conditions. The wall thickness of this kind of molecular sieve is in the range of 0.3 to 1.3 nm estimated from the repeat distance and the pore size.
