Nitrogen-doped titanium oxide on Indium tin oxide (ITO) coated glass substrate using DC magnetron sputtering. XRD, AFM, and UV-VIS-NIR spectroscopy measurements were done for structural and morphological changes before and after the annealing process. Wide band gap of TiO x N y /ITO range between is 2.77-3.57 eV occurred in the influence of ITO. Photodegradation on methylene blue was studied and the efficiency was 64.58% compared to 73% UV. Hence, ITO supports the optical band gap of the valance level shifting by the electrons. So the redox potential is enhanced, and the reaction of splitting is shifting to the visible region. The role of the ITO is to withdraw the electron, but the holes are actively participating in the photocatalytic reaction.
