NITROGEN AND COPPER DOPED SOLAR LIGHT ACTIVE TIO2 PHOTOCATALYSTS FOR WATER DECONTAMINATION

Abstract: A new category of photocatalytic coating that can degrade chemical as well as bacterial contaminants under visible sunlight wavelengths was generated by the deposition of a stable photocatalytic TiO2 film over the internal lumen of glass bottles by means of a sol–gel technique. Such a coating was produced either in doped or undoped form. This coating used copper and/ or nitrogen for producing visible light-active TiO2 films that were normalized or annealed at 600 ◦C and were characterized by Raman and X-ray photoelectron spectroscopy. The degradation of methylene blue was seen to accelerate with doped and undoped TiO2 films ...
