Annotation. Over the last decades nanophotocatalysts have found applications in a broad range of reactions including splitting of water to generate hydrogen fuel, dissociation of volatile organic pollutants, organic synthesis, sterilization of soils etc., because they are inexpensive, non-corrosive, environmental friendly, and stable under various conditions. In the present study we describe a new method of synthesising nanotechnology-based photocatalysts suspended in a liquid media and their application for water purification from chloro-organic pollutants and microbes. The nanophotocatalysts have been obtained using the electrolytic cell with graphite and titanium electrodes. The nanophotocatalysts have proved to form OH-radicals in presence of H2O molecules from the air during daylight hours under the sunlight ultraviolet radiation. The formed OH-radicals in a further stage react with organic pollutants. The paper discusses the data obtained for destruction of E.Coli, methyl orange, methyl blue, and polychlorinated biphenyls by nanophotocatalysts in a Petri dish in the ultraviolet spectrum of sunlight.
Keywords: nanophotocatalyst, photocatalysis, organic substance, sunlight.
