3. Assembly of mesoporous lamellar silicas with hierarchical particle architectures

Abstract

A novel assembly approach was used to prepare a porous lamellar silica with a hierarchical structure (MSU-V). This involved the cooperative formation of multilamellar vesicular surfactant-silica complexes, through the H-bondong interactions between H2N(CH2)12-NH2 as products of the tetraethylorthosilicate. Sorption properties of the lamellar MSU-V silica were similar to pillared lamellar clays.

5. Mesoporous titanosilicate molecular sieves prepared at ambient temperature by electrostatic (S+I-, S+X-I+) and neutral (SI) assembly pathways: a comparison of the physical properties and catalytic activity for peroxide oxidations

Abstract

The physical and catalytic properties of two titanium-substituted mesoporous catalysts prepared at ambient temperatures via electrostatic and neutral assembly pathways were compared. Specifically, Ti-MCM-41 and Ti-HMS molecular sieves were characterized with respect to their catalytic function in the liquid phase peroxide oxidations of methyl methacrylate, styrene, and 2,6-di-tert-butylphenol. The results demonstrated their superior catalytic efficiency over other titanium silicates.

7. Titanium-containing mesoporous molecular sieves for catalytic oxidation of aromatic compounds

Author

Tanev, Peter T., Chibwe, Malama, and Pinnavaia, Thomas J.

Subjects

Abstract

Mesoporous silica-based molecular sieves partially replaced with titanium are manufactured by templating. Titanium silicate materials exhibit catalytic activity toward oxidation of phenolic compounds and the transformation of benzene to phenol. The titanium silicate is a perfect molecular sieve catalyst in oxidizing alkanes and phenols.
