Photocatalytic degradation of Perchloroethylene by a lab-scale continuous-flow annular photoreactor packed with glass beads carbon-doped TiO2 nanoparticles

In this study, the amount of photocatalytic degradation perchloroethylene in gas phase was investigated by a fixed bed continuous-flow tubular photoreactor. The photoreactor consists cylindrical glass tube, filled with beads coated nanoparticles TiO2, TiO2 doped carbon (TiO2-C). These were synthesized sol-gel method and deposited on using dip technique. X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transforms infrared spectroscopy (FT-IR), diffuse reflectance (DRS) used for characterization materials. effect different parameters such as relative humidity, residence time, PCE concentration process ultraviolet irradiation to achieve highest possible efficiency. byproduct species monitored identified chromatography-mass spectrometer device (GC-MS). Under optimum experimental conditions, activities TiO2-C compared together. results showed that activity extremely increased when carbon. For catalyst, under UV (3000 ppm initial concentration, 30% humidity 1 min time) approximately 96% degraded.
