Abstract

The photodegradation efficiency (PE) of gaseous toluene was investigated by using titanium dioxide (TiO2) film doped of ruthenium (Ru)-dye/platinum (Pt) in a 3,600 L pilot reactor. Ru-dye was applied as a sensitizer to enhance PE of toluene in both UV and visible wavelength range since its major peaks are 225 nm, 325 nm, 375 nm, and 525 nm. PE by using Pt/TiO2 was more enhanced since Pt plays a role as an electron trapper in UV light range. The 3.2 μm thickness of TiO2 film was optimized for the highest PE. The highest PE was 75%, 85%, and 90% by TiO2, Pt/TiO2, and Ru-dye/Pt/TiO2 film, respectively.
