At this work we synthesized electrospun titanium oxide (TiO2) and nitrogen-doped titanium oxide (N-doped TiO2) for producing hydrogen (H2) in the same time pollutant removal from waste water by photocatalytic oxidation at room contitions.We use titanium isopropoxide (TiP)/polyvinylpyrrolidone (PVP) solution to prepare dispersed titanium oxide in polymer nanofibers by sol–gel processing and electrospinning techniques. TiO2 is a very effective and brillant photocatalyst for water treatment, but it has drawbacks like absorbing UV light and fast backward reaction and recombination between electrons and generated holes pairs, there are much effort has been devoted to overcome its problems, like doping with metals and non-metals. Advantage of N-doped TiO2 nano fiber is expanded the utilization of a large part of the solar spectrum. This might be useful for environmental and energy applications, such as the photocatalytic degradation of organic pollutants, solar cells, sensors, and water splitting reactions.The photocatalytic activity of TiO2 and N-doped TiO2 nanofibers was carried out in the waste and dye water-splitting reaction to produce H2 and water treatment using mercury light irradiation. The doping of TiO2 with Nitrogen, which should improve the electronic properties, leading to activation as a photocatalyst under visible light irradiation.several characterization techniques are employed for studying the surface morphology, phase of structure, and binding energy for TiO2 and N-TiO2 nanofibers (Scanning electron microscopy, X-ray diffractometry, transmission electron microscope).
