Abstract

This study examined the photodecomposition of volatile organic compounds (VOCs) using TiO₂ catalyst fabricated by the submerged arc nanoparticle synthesis system (SANSS). The TiO₂ catalyst was employed to decompose gaseous toluene and compared with Degussa-P25 TiO₂ in terms of decomposition efficiency. It was found that gaseous toluene exposed to UV irradiation produced intermediates that were even harder to decompose. After 60-min of photocomposition, Degussa-P25 TiO₂ reduced the concentration of gaseous toluene to 8.18% while the concentration after decomposition by SANSS TiO₂ catalyst dropped to 0.35%. The results show that TiO₂ prepared by SANSS has great efficiency in decomposing both gaseous toluene and its intermediates.
