Abstract

Prepared and heat-treated sol-gel ZnO-TiO₂ coatings onto microscope glass slides were characterised by atomic force microscopy (AFM), scanning electron microscopy (SEM), as well as absorption spectra of light has been obtained. Thermally treated xerogels were characterised by X-ray diffraction (XRD), as well as their photocatalytic activity using methyl orange (MO) and observing the colour changes over the time in visible light (VIS) and ultra violet (UV) light has been determined. The influence of ZnO concentration on morphology, photocatalytic activity and antibacterial properties of coatings were analysed. The growth of S. epidermidis on the surface of the samples was inhibited due to photocatalytic properties of coatings.
