Photocatalytic Degradation of Organic Pollutants in Air by Application of Titanium Dioxide Nanoparticles

Abstract

In this study we report of the synthesis and application of photocatalytic properties of titanium dioxide nanoparticles for cleaning of organic pollutants in the air on the example of organic pollutant – ethylene. Photocatalytic process, realized by application of titanium dioxide nanoparticles, has been carried in various time and temperature regimes in UV-reactor. By deep coating method the glass beads were coated by titan dioxide nanoparticles, which have been preliminarily obtained by sol-gel method. By gas chromatography method was determined 70% degradation of gaseous ethylene by the application of photocatalytic properties of TiO₂ nanoparticles.
