Abstract: A new heterogeneous photocatalyst was prepared by incorporation of methylene blue into ZSM-5 zeolite. This photocatalyst effectively absorbs light in visible range of the spectrum and when irradiated with visible light, it generates reactive oxygen species (ROS) in aqueous environment. Efficiency of the photocatalyst was tested on dechlorination of a model compound 4-chlorophenol and on growth inhibition of Gram-negative bacteria Escherichia coli.

Keywords: photocatalysis, zeolite, hydroxyl radical, methylene blue, Escherichia coli
