In this work, TiO₂ nanoparticles were synthesized using N₂-diluted and Oxygen-enriched coflow hydrogen diffusion flames. The effect of flame temperature on the characteristics of the formed TiO₂ nanoparticles was investigated. The measured maximum centerline temperature of the flame ranged from 2,103 K for oxygen-enriched flame to 1,339 K for N₂-diluted flame. The visible flame length and the height of the main reaction zone were characterized by direct photographs. The characteristics of synthesized TiO₂ nanoparticles were analyzed by SEM and TEM images. From these images, it was evident that the formed nanoparticles were divided into two sorts. In the higher temperature region, over the 1,700 K, TiO₂ nanoparticles having spherical shapes with diameters about 60 ㎚ were synthesized. In the lower temperature region, below the 1,600 K, the diameters of formed nanoparticles having unclear boundaries were ranged from 35 - 50 ㎚.
