Size tuning, functionalization, and reactivation of Au in TiO2 nanoreactors

Abstract

(Chemical Equation Presented) Reactor core: Hollow core-shell Au-TiO 2 nanocomposites can be prepared by a wet chemical method to form reactors that contain a catalyst core with a shell that is permeable to reactants. The core can be enlarged, and modification of the synthesis produces flowerlike nanostructures (see picture). Catalytic reactions in both the gaseous and liquid phase can be conducted in this type of photosensitized metal-semiconductor nanoreactor. © 2005 Wiley-VCH Verlag GmbH & Co. KGaA.
