ZnO nanorods (ZnO) are grown by Chemical Bath Deposition on microfiltration polyetheresulphone (PES) water membranes in order to combine photocatalytic properties of zinc oxide to adsorption properties of membranes. Degradation of a model dye (methylene blue, MB) dispersed in water is promoted by exposition of multifunctional ZnO/PES membranes to UV and solar light: in fact, ZnO decorated membrane ensures generation of reactive oxygen species (ROS) that degrade the organic pollutants dispersed in water. ZnO degradation promoted by UV irradiation is detectable by anionic meso-tetrakis(4-sulfonatophenyl) porphyrin (H2TPPS4-) that is used as effective molecular probe to sense the presence of Zn2+ ions due to photocatalytic leaching. © VBRI Press.
