The cotton fabrics with ZnO and ZnS NPs were structurally characterised by X-ray diffraction (XRD) using a Bruker-D2 PHASER instrument with Cu Kα radiation (λ = 1.5406 Å) in the range of 20° to 45° at 0.004°/s. Optical characterisation was performed by ultravioletvisible (UV-vis) spectra recorded with a S60 Libra (Biochrom) spectrophotometer. The morphologies of the ZnO and ZnS coated cotton fabrics were observed by scanning electron microscopy (SEM) using a TESCAN VEGA 4 microscope. Photocatalysis experiments were performed to analyse the disinfection potentials of these coatings. For this analysis, tissues with and without ZnO and ZnS NPs were immersed in a 10 mg.L -1 MB dye solution for 60 min to complete the dye adsorption step, and then were removed from the MB dye solution, dried, and exposed to a photoreactor UVC lamp (254 nm, 15 W, G15T8/OF, OSRAM). UV-vis absorption measurements were carried out at regular intervals in the period of 0-240 min.
