Abstract

The structures and photocatalytic activities of TiO2 and ZnO powder obtained by hydrothermal synthesis have been investigated in this work. We also compared the photocatalytic activity of obtained and prepared nanopowders. In addition, we measured the speed of photodegradation of organic compounds - rhodamine B for TiO2 and ZnO. At the beginning it was revealed that the clear liquid did not discolored by irradiation during 3 hours. These changes can be seen from the constructed spectra, the dependence of optical density on the duration of irradiation of a solution of Rhodamine B with TiO2 and ZNO.

Keywords: hydrothermal synthesis, photocatalysis, photodegradation, ultraviolet irradiation, organic dyes, optical density
