Abstract: This paper reported a novel method to prepare rutile TiO₂ nanoparticles. When TiCl₄ solution hydrolyzed, rutile TiO₂ nanoparticles can be prepared
at low temperature by adding a kind of organic additive into TiCl₄ solution.
XRD, FE-SEM and TG-DTA were used to analyze the influence of the amount of organic additives and the calcining temperature on the phase and particle
size of prepared nanoparticles. It was found that the best additive amount is
0.5 g/100 mL H2O, and the best calcining temperature is about 400 ℃. Being treated at the best condition, rutile TiO₂ nanoparticles (40~50 nm) can be obtained.
