Abstract

TiO₂ nanoparticles were synthesized by a homogeneous controlled precipitation method using industrial titanium sulfate (Ti(SO₄)₂). The obtained powders were characterized by X-ray diffraction (XRD), transmission electron microscope (TEM), Fourier transform infrared spectroscopy (FTIR) and ICP plasma spectrometer. EDTA was used as complexing agent to improve the purity and the formation of TiO₂ nanoparticles. Experimental results indicated that the high-purity TiO₂ nanoparticles were 20 nm in mean size and nearly monodispersed.
