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.

From Microporous to Mesoporous Molecular-Sieve Materials and Their Use in Catalysis
TL;DR: Corma et al. as mentioned in this paper used the Dupont Award on new materials (1995), and the Spanish National Award “Leonardo Torres Quevedo” on Technology Research (1996) on technology research (1996), to recognize the performance of zeolites as catalysts for oil refining and petrochemistry.

Delaminated zeolite precursors as selective acidic catalysts
TL;DR: In this paper, a layered zeolite precursor is delaminated, in much the same way as the layered structure of a clay may be unbound, and the result is an aluminosilicate whose catalytic sites are contained within thin, readily accessible sheets.

Epoxidation of Lower Olefins with Hydrogen Peroxide and Titanium Silicalite
M. G. Clerici,P. Ingallina +1 more
TL;DR: In this article, the epoxidation of lower olefins, catalysed by titanium silicalite (TS-1) under mild conditions, is reported. But the reaction may be performed at near room temperature, in dilute alcoholic or aqueous solutions of hydrogen peroxide.
