| Abstract: | In this paper,development of ultraviolet light emitting diode（UV-LED）/TiO2 device and their application for photocatalytic degradation of methylene blue were reported.The UV-LED with an output wavelength of 376 nm in UV-A band was applied as the UV light source for the photocatalytic decomposition of methylene blue.The decomposition of methylene blue in aqueous solution by TiO2 photocatalytic processes with the UV-LED was found to be technically and actually feasible,showing a promising technique for organic waste water treatment by the UV-LED/TiO2 method. |
