Реферат: Photocatalysis is a promising method for destruction of various toxic pollutants. TiO2 is the most active heterogeneous photocatalyst which is playing an important role in many industrial and technological processes. Unfortunately pure TiO2 is active only under the mild UV irradiation (<400 nm) which occupies only about 4% of the solar light spectrum. In order to utilize solar light efficiently in the visible region (>420 nm) which covers large range of the solar spectrum, the development of visible-light-driven photocatalysts has started over last decades. It is well known that uranyl ions in water could be synthesized by visible light and after excitation the oxidizing potential of uranyl ions becomes as high as 2,6-2,7 V. At the same time the gas phase photocatalytic oxidation of organic species with uranyl-modified photocatalysts is weakly investigated. The influence of spectral characteristics, uranyl quantity and nature of the support were the subject of current research.
