A thin layered TiO2 nanoparticles on a slide glass have a high potential for practical applications such as self-cleaning paint, florescent light bulb, tiles, automobile side mirrors, home applications, etc. In this study, a thin layered TiO2 particles were generated by a diffusion flame reactor, and the effects of process variables on the properties of TiO2 particles were investigated. Column shape TiO2 particles were characterized by RS(Raman Spectroscopy), SEM(Scanning Electron Microscope), and XRD(X-ray Diffraction), TEM(Transmission Electron Microscopy. As the inlet fuel/O2 ratio and TTIP concentration increased, the TiO2 particle size increased. Meanwhile, the particle size decreased as the total gas flow rate increased due to the decreased residence time. As the TiO2 particle size decreased, a specific surface area increased.
