[FeII(bpy)3]2+/TiO2-codoped zeolites: synthesis, characterization, and first application in photocatalysis

TiO2-codoped [FeII(bpy)3]2+/zeolite Y systems are revealed to be efficient photocatalysts for photochemically enhanced Fenton processes. Preparation, characterization, and tests using 2,4-xylidine as a model pollutant are described, and a first mechanistic hypothesis explaining the rather high photochemical reactivity of the catalyst system is given.
