The exposure of TiCl3 to the plasma electric discharge burned in moisten air lead to the formation of TiO2 nanopowder for short exposure time (<30 min). However, as expected for longer exposure time, the N-doped TiO2 was formed. The synthesized powder for three exposure times was characterized by X-ray diffraction (XRD), FTIR spectroscopy, and nitrogen physisorption. The nitrogen loading was confirmed by X-ray photoelectron spectroscopy (XPS) analysis and the redshift response of doped photocatalyst was evaluated through the discoloration of aqueous Remazol Brilliant Blue-R dye under daylight. As a result, the textural analysis revealed the mesoporous materials with a specific surface area of 157 m(2) g(-1). The chemical states of nitrogen have been assigned to N-Ti-O and O-N-O in the TiO2 lattice. The photo degradation rates of RBB-R dye were 62; 76 and 81%, respectively, for the sample exposed during 20, 30 and 60 min. The observed enhanced photocatalytic activity is mainly attributed to the increasing amount of Nitrogen loaded that shift the photocatalytic response in the visible region of light.
