In this work, TiO₂ nanoparticles were synthesized using N₂-diluted and Oxygen-enriched coflow hydrogen diffusion flames. The effect of flame temperature on the crystalline structure of the formed TiO₂ nanoparticles was investigated. The measured maximum centerline temperature of the flame ranged from 2,103K for oxygen-enriched flame to 1339K for N₂-diluted flame. The visible flame length and the height of the main reaction zone were characterized by direct photographs. The crystalline structures of TiO₂ nanoparticles were analyzed by XRD. From the XRD analysis, it was evident that the crystalline structures of the formed nanoparticles were divided into two sorts. In the higher temperature region, over the 1,700K, the fraction of formed TiO₂ nanoparticles having anatase-phase crystalline structure increased with increasing the flame temperature. On the contrary, in the lower temperature region, below the 1,600K, the fraction of anatase-phase nanoparticles increased with decreasing the flame temperature.
