Highly homogeneous nitrogen doped titania nanomaterials: Synthesis and characterization

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. © 2016 penerbit utm press. all rights reserved.
