| 摘 要： | Progressively more stringent environmental regulations have created a growing demand for developing processes to degrade both gaseous and aqueous contaminants in a more environmental-safe and cost effective manner. In the past decade, TiO2-based photocatalysis has been consid-ered to be a promising candidate for environmental puri-fication applications due to the powerful oxidation strength, chemical stability and nontoxicity of TiO21,2]. For continuous use of it in photocatalysis to the rem…

| Abstract: | By means of TiO2-1ayer-on-SiO2-1ayer, anatase TiO2 was deposited on novel side-glowing optical fibers, which can provide side UV radiation along the whole fiber length. FE-SEM images show that the double layers adhered well to the side-glowing optical fiber, and the TiO2, coating was homogeneous and smooth. The decomposition reaction of reactive brilliant red dye X-3B on a single TiO2-coated side-glowing optical fiber indicated that the side-scattering UV light intensity was strong enough for photocatalytic oxidation reaction. Therefore, TiO2-coated side-glowing optical fibers open up a new way to use the optical fiber reactor in photocatalytic wastewater treatment. |
