A series of nitrogen doped titania nanomaterials were synthesized via sol-gel method by using tetraethyl ammonium hydroxide as N source. Doping of N into TiO2 was confirmed via X-ray diffraction (XRD) and fourier transform infrared spectroscopy (FTIR) analyses. Mixture of anatase and rutile phases appeared in the unmodified TiO2 which was calcined at 773 K. The addition of N to TiO2 matrix led to formation of single phase of anatase. It has been demonstrated that TiO2 and all the N-doped TiO2 materials were in nanoscale ranging 15.91 – 20.82 nm. Change in surface morphology after N doping was detected by field emission scanning electron microscope (FESEM). Results of EDX mapping analysis indicated homogeneous distribution of N dopants.
