TL;DR: In this paper, the synthesis, characterization, and proposed mechanism of formation of a new family of silicatelaluminosilicate mesoporous molecular sieves designated as M41S is described.

Development of a formation mechanism for M41S materials
James C. Vartuli,Kirk D. Schmitt,C.T. Kresge,W.J. Roth,M. E. Leonowicz,S.B. McCullen,S.D. Hellring,J.S. Beck,J. L. Schlenker,D.H. Olson,E. W. Sheppard +10 more
TL;DR: The influence of surfactant/silica molar ratio(Sur/Si) in M41S syntheses was studied in the simple synthesis system consisting of tetraethylorthosilicate (TEOS), water, and the cetyltrimethylammonium(CTMA) cation at 100°C.
Book ChapterDOI
Designed Synthesis of Mesoporous Molecular Sieve Systems Using Surfactant-Directing Agents
James C. Vartuli,Charles T. Kresge,W.J. Roth,S.B. McCullen,J.S. Beck,Kirk D. Schmitt,M. E. Leonowicz,J.D. Lutner,E. W. Sheppard +8 more
TL;DR: The use of cationic surfactants as structure directing agents has resulted in the discovery of M41S, the first, ordered mesoporous molecular sieves as discussed by the authors, which exhibit hexagonal, cubic or lamellar structure.
