Understanding the acid behavior of zeolites from theory and experiment
Article Abstract:
The relationship between acidity and catalytic activity of a zeolyte was studied by using a heterogenous catalytic reaction between a hydrocarbon and an acid zeolyte. Infrared spectroscopy was used in the observations and quantum chemical techniques were utilized to calculate the reaction mechanisms and the relationship in question. A detailed profile of this process was generated by comparing the theoretical results and experimental observations.

Sn-zeolite beta as a heterogeneous chemoselective catalyst for Baeyer-Villiger oxidations
Article Abstract:
Incorporating 1.6 weight per cent tin into the framework of zeolite beta allows it to function as a heterogeneous catalyst for the Baeyer-Villiger oxidation of saturated and unsaturated ketones by hydrogen peroxide. It is suggested that the first stage of the reaction involves the activation of the carbonyl-group of the ketone on the Sn atoms of the Sn-zeolite beta.

How green was my ester
Article Abstract:
It has been possible to produce a new class of catalysts for the Baeyer-Villiger oxidation of ketones. This involves transforming a ketone into an ester by using hydrogen peroxide as an organic oxidant. The catalysts are insoluble in water and in all organic solvents, with the reaction arising at the interface between the solid catalyst and the liquid solution.
