Zeolite-based photocatalysts.

The compartmentalised intracrystalline void space of zeolites are specially suited to incorporate and organise photoactive guests that can be used as photocatalysts. The rigid micropores allow assembly of multicomponent systems comprising of antenna and relays reminiscent of natural photosynthetic centers. Besides inorganic metal oxide clusters, zeolites as host are particularly attractive to construct organic photocatalysts since the guest becomes significantly stabilized by incorporation. This review gives special emphasis to the commercial and potential application of photocatalysts.
