| Abstract |
In this discuss, using photocatalytic reaction to remove VOCs, survey the impact of photocatalyst reactor on the VOCs. The photocatalyst reactor is a new type of TiO2 thin films/glass fiber photocatalyst reactor and UV light system to remove VOCs, the element is by fill up TiO2 thin films/glass fiber coating around the UV light. The coating method of TiO2 films is the use of sol-gel technique. Use X-ray diffractometry (XRD)ĦBEngy-Dispersive X-Ray Spectroscopy (EDS) and Scanning Electron Microscopy(SEM) observed structure and detection of TiO2 thin films. VOCs module system set up their own for the laboratory, acetone used as the sample gas, and use gas detection instrument(minirae 2000) detectable concentrations. In the control of the flow rate and concentration, photocatalytic reactor measurement of VOCs removal efficiency. The results showed that the glass fibers are coated with TiO2 films, and take shape anatase, diameter is 10-50 nm. In the irradiation of 365nm UV light, the TiO2 thin films/glass fiber photocatalyst reactor to removal of VOCs can be achieved 90%. In this discuss, also added porphyrin(TCPP) to increase TiO2 thin films/glass fiber for the visible light absorbance. Use this Methods to increase application range. |
