摘要：

In this work the photoactive properties of the aqueous suspension containing ZnO nanoparticles and zinc nitrate have been studied. The mechanism of organics photodecomposition at the presence of prepared suspension was studied by the measurements of spectral dependencies of Chicago Sky Blue dye photodecomposition. It was found that dye photodecomposition proceeds in three different photochemical processes: 1) the direct photodecomposition of organic molecules; 2) oxidation of dye molecules by reactive oxygen species which are the product of nitrate anions photodecomposition; 3) photocatalytic action of ZnO nanoparticles.
