Sekundarni naslov: | Immobilization of TiO2 nanostructured microparticles |
Sekundarni povzetek: | Titanium tetrachloride was used as a precursor for the synthesis of three-dimensional flower-like TiO2 microparticles, from which three different suspensions were further prepared. The suspensions were deposited in a different number of layers to the glass slides, which were then heat-treated. The prepared plates were used for the photocatalytic degradation of Plasmocorinth B in a batch reactor under UV light and under different conditions. The photocatalytic degradation of the dye was checked by measuring the absorption of the samples with a spectrophotometer. A detailed insight into the morphology and structure of the photocatalyst was obtained with the scanning electron microscope. The results showed that polyvinylpyrrolidone proved to be the best binder as the resulting suspension in the form of layers and after heat treatment degrades the dye the fastest. The degradation of the dye was also accelerated by three layers of the suspension deposited on the glass slides and by purging the aqueous dye solution with oxygen. |
