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.
