Photocatalytic Performance of CPC Photoreactor in Presence of Anatase/Rutile TiO2 Mixed Phase
Keywords:Titanium dioxide, Sonochemical, CPC reactor
Titanium dioxide mixed phase of anatase and rutile was prepared via sol-gel process with ultrasound assistance then calcined at different temperatures to obtain mixed phase TiO2. The mixed phase TiO2 with specific ratio was used as photocatalyst in compound parabolic collecting (CPC) photoreactor. X-ray absorption spectroscopy (XAS) and X-ray photoelectron spectroscopy (XPS) were employed to investigate the phase transformation of TiO2. Photoactivities of the prepared photocatalysts were performed to decolorize the organic dye solution by coating on solid glass spherical beads which were packed in CPC photoreactor to study the performance of photodegradation. The results indicate that the system can be practically utilized and the cleaning is required for the next use.
