Photodegradation of Toluene by TiO2 Nanoparticles by Flame CVD Process

Abstract:

Article Preview

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.
