The light absorption onset shifts from 380 nm on pure TiO2 to the visible region at 550 nm with N-TiO2. A clear decrease in the band gap and the nitrogen 2p states on the top of the valence band on N-TiO2 (compared to TiO2) is deduced from the optical absorption spectroscopy results. The chemical nature of N has been evolved as N-Ti-O in the anatase TiO2 lattice as identified by X-ray photoelectron spectroscopy (XPS). Photocatalytic decomposition of methylene blue has been carried out both in the UV and in the visible region and N-TiO2 shows higher activity than the Degussa P25 TiO2 photocatalyst in the visible region.</p>1 aSathish, M1 aViswanathan, B1 aViswanath, RP1 aGopinath, Chinnakonda, S.  uhttps://library.ncl.res.in/content/synthesis-characterization-electronic-structure-and-photocatalytic-activity-nitrogen-doped
