Paper Title:
Preparation of Nano-Sized TiO2 Particles by Self-Propagating-High-Temperature Synthesis
  Abstract

This investigation was aimed at preparing nanocrystalline TiO2 powder by self-propagating-high-temperature synthesis. Titanium (IV) n-butoxide was hydrolyzed to obtain titanl hydroxide [TiO(OH)2], and titanyl nitrate [TiO(NO3)2] was obtained by reaction of TiO(OH)2 with nitric acid. Finally, the aqueous solution containing titanyl nitrate [TiO(NO3)2] and a fuel, urea, were mixed and combusted to obtain the nano-sized titania. The anatase TiO2 nanocrystalline ( ~56nm) with high BET surface area( 280 m2g-1) and narrow band gap energy( 2.7 eV) were thus obtained.
