In this work, the synthesis and characterization of chloride free nitrogen doped TiO2 nanoparticles have been undertaken. The chloridefree nitrogen doped TiO2 nanoparticles were hydrothermally prepared by mixing acidic ethylene diamine solution with titanium tetraisopropoxide followed by heating at 120 and 150 °C for 12 h and 180 °C for 6 h. The resulted solid was isolated, dried, grinded and calcined at 450 °C for 3 h. The samples were characterized using powder X-ray diffraction, UV-visible reflectance and SEM-EDAX methods. The results indicated that the samples consist of a major component of rutile and minor anatase types. The hydrothermal temperature does not affect to the composition of the product. The N-doped in TiO2 decreases the lattice parameters. The crystallite size of rutile is somewhat bigger than anatase. As expected, all samples are free of chloride. © 2018 Chemical Publishing Co.
