摘要：
The present study is directed to clarify the influence of the ratio of TiO2 to ZnO, containing in the nanocomposite powder samples, on their activity as photocatalysts in slurry. A series of samples corresponding to different percentages of titania are prepared from commercial brands. The phase composition and crystallinity of the samples is characterized by X-ray diffraction. The surface morphology of the samples is observed via scanning electron microscope. The photocatalytic action of the composites is tested in UV and visible light induced degradation of two model pollutants: azo dye Orange II (O II) used as cosmetic colorant CI 15510 and triarylmethane dye Brilliant Green (BG), used as food colorant E142.
