Synthesis and characterization of nitrogen doped titania nanomaterials of homogeneous particle size
Modification of sol gel method was used to synthesize homogeneous particle size nitrogen doped titania (N-TiO2) nanomaterials using etraethyl ammonium hydroxide as N source. XRD analysis showed that these N-TiO2 (1-5 % N concentration) crystallined in anatase structure. The crystallinity of the samp...

| Summary: | Modification of sol gel method was used to synthesize homogeneous particle size nitrogen doped titania (N-TiO2) nanomaterials using etraethyl ammonium hydroxide as N source. XRD analysis showed that these N-TiO2 (1-5 % N concentration) crystallined in anatase structure. The crystallinity of the samples decreased with increasing of N content. The calculation using Scherer equation showed that the particle size of the synthesized N-TiO2 ranged 15.02-26.85 nm, strongly suggesting attainment of nanomaterials. DR UV-Vis results indicated that the band gap energy of 5% N doped TiO2 was only 2.58 eV, implying the sample could be a potential photocatalyst under visible light irradiation. Homogeneous particle size of the synthesized nanomaterials was evidenced through FESEM images. Meanwhile, the EDX analysis confirmed the homogenous distribution of elements Ti, N and O in 5% N doped titania sample. |
