TiO2 nanoparticle generation by flame pyrolysis FFESS system

Generation of TiO₂ nanoparticles is demonstrated by using a flame pyrolysis FFESS system which combines flame aerosol synthesis with the flow-limited field-injected electrostatic spraying (FFESS) technique. In this work, well-dispersed TiO₂ nanoparticles are generated without particle coalescence, which are well-suited for forming high surface area porous TiO₂ nanoparticle networks for photocatalysts and nano structured solar cells such as dye-sensitized solar cells. Flame pyrolysis FFESS generates TiO₂ nanoparticles exhibiting a narrow size distribution, and can control the ratio of anatase and rutile phase. The results demonstrate that flame pyrolysis FFESS is a promising technology for enabling more versatility in generating nanostructures of various materials.
