The determination of design and operational conditions of ultraviolet light-emitting diode (UV-LED)/TiO2 device is the major concern for the development and potential application of the photocatalytic process. In this article, development of UV-LED/TiO2 device and their applications for photocatalytic degradation of methylene blue (MB) are reported. The UV-LED with an output wavelength of 376 nm was applied as the UV light source for the photocatalytic decomposition of because of. The photocatalytic behavior of the photocatalytic decomposition of because of in aqueous solution operated by the UV-LED/TiO2 device was studied under various conditions including initial dye concentration, the mass of catalyst, light power, and pH value. The decomposition of because of in aqueous solution by TiO2 photocatalytic process with the UV-LED was found to be technically and actually feasible. Besides, our results show a promising technique for organic waste-water treatment by the UV-LED/TiO2 method.
