Jeffrey S. Beck,James C. Vartuli,Wieslaw J. Roth,M. E. Leonowicz,Charles T. Kresge,Kirk D. Schmitt,Cynthia Ting-Wah Chu,David H. Olson,E. W. Sheppard,S. B. McCullen,J. B. Higgins,J.L. Schlenker +11 more
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.
Journal ArticleDOI
Small angle neutron scattering study of the structure and formation of MCM-41 mesoporous molecular sieves
C. J. Glinka,M. Nicol,Galen D. Stucky,E. Ramli,David I. Margolese,Qisheng Huo,J. B. Higgins,M. E. Leonowicz +7 more
TL;DR: The nanoscale structure and synthesis mechanisms of the MCM-41 class of inorganic mesoporous materials have been investigated by small angle neutron scattering (SANS) measurements with solvents imbibed in the pores to vary the scattering contrast as discussed by the authors.
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.
Book ChapterDOI
A New Family of Mesoporous Molecular Sieves
S. B. McCullen,James C. Vartuli,Charles T. Kresge,Wieslaw J. Roth,Jeffrey S. Beck,Kirk D. Schmitt,M. E. Leonowicz,J.L. Schlenker,Stuart S. Shih,J.D. Lutner +9 more
TL;DR: The M41S family of materials represent the first mesoporous molecular sieves as discussed by the authors, with high pore volumes and surface areas exhibiting an array of structures that are thermally stable inorganic analogs of organic, lyotropic liquid crystalline phases.
