Photodegradation of Toluene by TiO₂ Nanoparticles by Flame CVD Process

Abstract:

Photo-degradation of toluene at ppb levels by mixed-phase TiO₂ nanoparticles, synthesized by the oxidation of TiCl₄ in propane/air flame chemical vapor deposition (CVD) process, has been investigated experimentally by using a tubular photoreactor with thin TiO₂ films coated on the reactor wall by sedimentation. Effects of toluene at initial concentration at ppb levels, rutile mass fraction and photoluminescence (PL) spectra of TiO₂ nanoparticles on degradation degree have been investigated under the conditions of 5.7 seconds of residence time, 70% relative humidity, 38mg/cm² of TiO₂ loading, 25mW/cm² of irradiation with main wavelength of 254nm.
