X-Ray Diffraction Structure Analysis of MCM-48 Mesoporous Silica. —
The structure of the title mesoporous silica is characterized from XRD data by applying
recently developed methods of mesostructure analysis and full-profile refinement. The
pore wall thickness of both as-made and calcined MCM-48 is 8.0 Å. No regular variations of the wall thickness exist, but its density is ca. 10% higher in the low-curvature
regions. A new extended model function of the density distribution in MCM-48 is
proposed. — (SOLOVYOV*, L. A.; BELOUSOV, O. V.; DINNEBIER, R. E.;
