Abstract:

Scope of research. Mn(Ag)-containing nanocomposites of the ZnO-ZnAl2O4 system synthesized by the polymer-salt method. The purpose. Obtaining new photocatalytic composites, studying the possibility of their application for photocatalytic decomposition of organic pollutants using Chicago Sky Blue dye as an example, and studying their antibacterial activity against Staphylococcus aureus ATCC 209P bacteria. Method. The obtained samples were examined using scanning electron microscopy, X-ray diffraction analysis, diffuse reflectance spectroscopy and photoluminescence spectroscopy. Main results. The results show that the composites consist of 30–40 nm hexagonal zincite nanocrystals and 30 nm cubic gahnite nanocrystals. The synthesized composites have the ability to photogenerate chemically active singlet oxygen and antibacterial activity, and also demonstrate photocatalytic activity under the influence of ultraviolet radiation. Practical significance. The obtained photocatalytic bactericidal composites can be used to purify aquatic environments from organic pollutants and pathogenic microorganisms.
