Synthesis of titanoaluminosilicates isomorphous to zeolite Beta, active as oxidation catalysts
268
TL;DR: In this article, the incorporation of Ti to the low aluminum-containing zeolite Beta framework has been characterized by XRD, i.r., and thermal analysis, and the large pores of [Al, Ti]-Beta compared to TS-1 allow the use of this material as a catalyst in the selective oxidation of cyclododecane with hydrogen peroxide.

Lewis acids as catalysts in oxidation reactions: from homogeneous to heterogeneous systems.
TL;DR: This review is focused on the use of solid Lewis acids to promote catalytic oxidations, and the core of the review is organized to show the evolution from the simplest strategy for heterogeneizing homogeneous catalysts, to the more elaborate ones in which the active sites are part of the solid structure.

Microporous Crystalline Titanium Silicates
TL;DR: In this paper, the authors focused on the microporous crystalline titanium silicates and their catalytic properties in H2O2 oxidation reactions and attributed the unusual properties of titanium silicalites have been attributed to the presence of TiIV in framework positions of the SiO2 lattice.

Structural and Physicochemical Features of Titanium Silicalites
TL;DR: In this article, a comparison and discussion of the substantial amount of information about the state and coordination of titanium ions in titanium silicalites is presented, with emphasis on location of the Ti ions in framework or extra-framework positions, their coordination, and the relationship of some spectral features to concrete structures at the atomic level.

Oxyfunctionalization of alkanes with hydrogen peroxide on titanium silicalite
TL;DR: In this paper, it was shown that titanium silicalite, a microporous crystalline Ti-silica, is able to activate secondary and tertiary carbon atoms in alkanes, so that they may be oxidized to alcohols and subsequently to ketones using aqueous H2O2.

Titanium-Silicalite: a Novel Derivative in the Pentasil Family
TL;DR: In this article, a novel Ti derivative of Silicalite-1 has been prepared by hydrothermal procedure with (n-C 3 H 7 )N-OH, and X-ray, IR, EDX, and 29 Si MAS NMR investigations indicate an homogeneous distribution of Ti in the crystal while suggesting replacement of Ti for Si in the framework.
