The Procedure and Crystallization Factors of MCM-41-based Crystalline Mesoporous Molecular Sieves

MCM-41-based crystalline mesoporous molecular sieves are of great academic and practical importance to such fields as heterogeneous catalysis,absorption stripping,composites and nano-materials science. These materials may be prepared by involving the micella of long-chain quaternary ammonium salt, primary amine, geminal amine or polyethylene surfactants as templating species. In this paper the new achievements and progress of mesoporous materials,mainly MCM-41 are reviewed and summarized. The procedures of MCM-41 are introduced and the main factors influencing crystallization of MCM-41 discussed.
