Abstract
Highly specific catalyst compositions are provided, comprising zeolites containing a photoassisting material, which is capable of catalyzing photoassisted heterogenous catalytic reactions within the zeolite structure. The photoassisting material can be sorbed by the zeolite or incorporated directly within the zeolitic framework.
Claims22
A method of catalyzing highly specific photochemical reactions in a reaction system by incorporating a photoassisting species within a zeolite catalyst to form a catalyst composition, which method comprises:
- exposing the catalyst composition to radiant energy selected from the group consisting of ultraviolet radiation and visible light while simultaneously contacting the catalyst composition with one or more reactants, and removing the resulting products from the reaction system.
